[JDK 6u21]: does CMS report concurrent mode failure on perm gen expansion ?
by Charlie Hunt 05 Dec '18

05 Dec '18

I'm looking at a GC log and surprised by the "concurrent mode failure" messages. I'm seeing the following GC log entries as the first 8 GCs: 3.398: [Full GC 3.398: [CMS (concurrent mode failure)[YG occupancy: 594957 K (1887488 K)]3.489: [weak refs processing, 0.0000140 secs]: 0K->0K(6291456K), 0.1308660 secs] 594957K->594957K(8178944K), [CMS Perm : 21247K->21247K(21248K)], 0.1310260 secs] [Times: user=0.13 sys=0.03, real=0.14 secs] 3.529: [Full GC 3.529: [CMS (concurrent mode failure)[YG occupancy: 594957 K (1887488 K)]3.617: [weak refs processing, 0.0000110 secs]: 0K->0K(6291456K), 0.1010290 secs] 594957K->594957K(8178944K), [CMS Perm : 21248K->21248K(42496K)], 0.1011530 secs] [Times: user=0.12 sys=0.00, real=0.10 secs] 3.638: [Full GC 3.638: [CMS (concurrent mode failure)[YG occupancy: 662071 K (1887488 K)]3.730: [weak refs processing, 0.0000140 secs]: 0K->0K(6291456K), 0.1068710 secs] 662071K->662071K(8178944K), [CMS Perm : 21319K->21319K(42688K)], 0.1069610 secs] [Times: user=0.15 sys=0.00, real=0.11 secs] 3.772: [Full GC 3.772: [CMS (concurrent mode failure)[YG occupancy: 729184 K (1887488 K)]3.915: [weak refs processing, 0.0000140 secs]: 0K->0K(6291456K), 0.1582170 secs] 729184K->729184K(8178944K), [CMS Perm : 21499K->21499K(42880K)], 0.1583500 secs] [Times: user=0.20 sys=0.00, real=0.16 secs] 3.962: [Full GC 3.962: [CMS (concurrent mode failure)[YG occupancy: 804686 K (1887488 K)]4.107: [weak refs processing, 0.0000130 secs]: 0K->0K(6291456K), 0.1598050 secs] 804686K->804686K(8178944K), [CMS Perm : 21702K->21702K(43072K)], 0.1599420 secs] [Times: user=0.21 sys=0.00, real=0.16 secs] 4.497: [Full GC 4.497: [CMS (concurrent mode failure)[YG occupancy: 939150 K (1887488 K)]4.672: [weak refs processing, 0.0000130 secs]: 0K->0K(6291456K), 0.1895350 secs] 939150K->939150K(8178944K), [CMS Perm : 22202K->22202K(43408K)], 0.1896680 secs] [Times: user=0.23 sys=0.00, real=0.19 secs] 5.054: [Full GC 5.054: [CMS (concurrent mode failure)[YG occupancy: 992483 K (1887488 K)]5.274: [weak refs processing, 0.0000130 secs]: 0K->0K(6291456K), 0.2347170 secs] 992483K->992483K(8178944K), [CMS Perm : 24058K->24058K(44408K)], 0.2348700 secs] [Times: user=0.28 sys=0.00, real=0.23 secs] 6.662: [Full GC 6.662: [CMS (concurrent mode failure)[YG occupancy: 1292895 K (1887488 K)]6.953: [weak refs processing, 0.0000140 secs]: 0K->0K(6291456K), 0.3063690 secs] 1292895K->1292895K(8178944K), [CMS Perm : 30692K->30692K(48120K)], 0.3065860 secs] [Times: user=0.66 sys=0.01, real=0.30 secs] After these 8 GCs, the GC log is much inline with what I'd expect, i.e. ParNew GCs, initial-marks, remarks, etc. In each of the above GCs: - young gen is increasing in occupancy - old gen remains empty - perm gen space size is expanding I can understand the Full GC being reported since perm gen is expanding, but I don't understand the reporting of "concurrent mode failure". Am I missing something? Is it possible HotSpot is reporting concurrent mode failure when perm gen is expanding? Here's the set of command line options in use: -Xmx8G -Xms8G -Xmn1500m -XX:+UseCompressedOops -XX:-UseGCOverheadLimit -XX:+UseConcMarkSweepGC -XX:MaxDirectMemorySize=5000m thanks, charlie ... PS: I didn't go look at / investigate OpenJDK HotSpot source code since this is JDK 6u21 and thought it might be possible something may have changed between 6u21 and what's in OpenJDK.

Request for review (small) 8026303: CMS: JVM intermittently crashes with "FreeList of size 258 violates Con,servation Principle" assert
by Jon Masamitsu 12 Aug '14

12 Aug '14

8026303: CMS: JVM intermittently crashes with "FreeList of size 258 violates Con servation Principle" assert CompactibleFreeListSpace:: par_get_chunk_of_blocks() replenishes the free list of a given size by splitting a larger chunk. The code searched for a block that was large enough to split. If a large enough chunk was found it was removed from the dictionary and a split death was recorded. If the remainder after splitting would be too small, that block was returned to the dictionary but forgot to fix the split death accounting The fix was to move the split death accounting to the point where it was known that the chunk would not be put back into the dictionary. There was also code moved which did the accounting for the _unallocated_block (updated it to account for the allocation which could change _unallocated_block). The fix http://cr.openjdk.java.net/~jmasa/8026303/webrev.00/ A small amount of code refactoring was done and is in a second webrev (along with the fix above). Both changes will be put back together. http://cr.openjdk.java.net/~jmasa/8026303/webrev_cleanup.00/ Thanks. Jon

RFR(S/M): 7132678: G1: verify that the marking bitmaps have no marks for objects over TAMS
by John Cuthbertson 29 Apr '14

29 Apr '14

Hi Everyone, Can I have a couple of volunteers review the changes for this CR? The webrev can be found at: http://cr.openjdk.java.net/~johnc/7132678/webrev.0/ Most of the changes come from a patch that Tony gave me before he left and I had to tweak them slightly to remove a spurious failure. The changes verify that the heap regions don't have any marks between [TAMS, top) at strategic places: start and end of each GC, start and end of remark and cleanup, and when allocating a region. Tony deserves the bulk of the credit so, if possible and there are no objections, I intend to list him as author of the change and include myself as a reviewer. Testing: GC test suite with the both the new flags (separately and together) and a low IHOP value. jprt with the new flags (+IgnoreUnrecognizedVMOptions so that product test runs did not fail). Thanks, JohnC

JDK-7090324: gclog rotation via external tool
by Yasu 05 Mar '14

05 Mar '14

Hi all, We are using "logrotate" tool on RHEL for various log rotation. Current HotSpot has gclog rotation function for log size base, however I need to rotate gc log synchronizing with logrotate tool. So I've created RFE as "JDK-7090324: gclog rotation via external tool" . And Sr. Engineering Manager in Oracle said he use the essence of my patch in one of the jcmd subcommands. http://mail.openjdk.java.net/pipermail/hotspot-gc-dev/2011-September/003274… 2 years ago, I posted a patch for this RFE. But this patch is too old to apply for current HotSpot. In last month, a similar discussion was appeared in ML. So I think it's time to discuss this RFE. http://mail.openjdk.java.net/pipermail/hotspot-gc-dev/2013-August/008029.ht… Please cooperate. Best regards, Yasumasa

Better default for ParallelGCThreads and ConcGCThreads by using number of physical cores and CPU mask.
by Jungwoo Ha 09 Jan '14

09 Jan '14

Hi, I am sending this webrev for the review. (On behalf of Jon Masamitsu, it is upload here) http://cr.openjdk.java.net/~jmasa/8028554/webrev.00/ The feature is a new heuristics to calculate the default ParallelGCThreads and ConGCThreads. In x86, hyperthreading is generally bad for GC because of the cache contention. Hence, using all the hyper-threaded cores will slow down the overall GC performance. Current hotspot reads the number of processors that the Linux reports, which treats all hyper-threaded cores equally. Second problem is that when cpu mask is set, not all the cores are available for the GC. The patch improves the heuristics by evaluating the actual available physical cores from the proc filesystem and the CPU mask, and use that as the basis for calculating the ParallelGCThreads and ConcGCThreads. The improvements of GC pause time is significant. We evaluated on Nehalem, Westmere, Sandybridge as well as several AMD processors. We also evaluated on various CPU mask configuration and single/dual socket configurations. In almost all cases, there were speed up in GC pause time by 10~50%. We primarily use CMS collector for the evaluation, but we also tested on other GCs as well. Please take a look and let me know if this patch can be accepted. Thanks, Jungwoo Ha

RFR(s): 8029162: G1: Shared SATB queue never enabled
by Per Liden 08 Jan '14

08 Jan '14

Summary: When activating/deactivating the G1 pre-barrier all SATB queues are looped through and have their active state set accordingly. There is one queue per Java thread and a shared queue for all non-Java threads. The loop done to set the active state of all queues forgets to set the active state on the shared queue. I suspect this was missed because the logic in SATBMarkQueueSet::set_active_all_threads() is mixed with quite a bit of verification code. This patch also moves this verification code out into a separate function. Testing done: jprt, kitchensink (10 hours), gcbasher (10 hours) http://cr.openjdk.java.net/~pliden/8029162/webrev.0/ https://bugs.openjdk.java.net/browse/JDK-8029162 cheers, /Per

RFR(s): 8029255: G1: Reference processing should not enqueue references on the shared SATB queue
by Per Liden 08 Jan '14

08 Jan '14

Summary: A side effect of fixing JDK-8029162 (G1: Shared SATB queue never enabled) is that the reference processor will start to add references to the shared SATB queue when enqueuing discovered references. This will later cause ConcurrentMark::verify_no_cset_oops() to fail because we now have enqueued references in the SATB qeueue which points into the collection set (which will be empty after the collection). This patch makes sure we avoid doing pre-barriers, by instead doing raw stores followed by a post-barrier. This patch also removes an unused constructor and the unnecessary caching of the barrier set in the ReferenceProcessor. So use of _bs was replaced by oopDesc::bs(). Further, the cached barrier set was only set/used if discovered_list_needs_barrier was true, but with this change we will need the barrier set in other cases too. Testing done: jprt, kitchensink (10 hours), gcbasher (10 hours) http://cr.openjdk.java.net/~pliden/8029255/webrev.0/ https://bugs.openjdk.java.net/browse/JDK-8029255 cheers, /Per
