Question about GC and network throughput problems
by George Porter 20 May '09

20 May '09

Hello everyone, I'm writing with a question on behalf of the Apache HBase project, which is an open-source implementation of Google's BigTable system, written in 100% Java. One of the developers ran into the following problem, and I wasn't sure where to look, and so I was hoping that someone on this list might have some pointers or suggestions that I could try. Thank you in advance for your time, George "I was wondering if you could help us out w/ some issues we're having performance-wise. The areas we need to look at next are rpc and the garbage collector. The rpc we can handle ourselves. I was wondering if you could point us at someone who could help with the latter. Maybe you know some java GC expert who is up to the challenge? GC pauses hamper upload rates -- halving or quartering over time -- and pauses mid-fetch bring our overall fetching throughput down as well as latency. Some time has been spent messing w/ GC options, using different engines and different tunings to some effect (so far, we're seeing one engine to upload but need another to serve), but we're not expert and we're supposed to be a 'general-use' application fielding uploads and serving concurrently." They are using Java 1.6.0_14 running on Linux x86_64. _______________________________________________ hotspot-gc-use mailing list hotspot-gc-use(a)openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/hotspot-gc-use

frequent full GC: why?
by Anuj Lal 19 May '09

19 May '09

Jdk version 1.5.0_16rev9 What can the cause of full gc back to back?. We are seeing frequent full GC even though enough space there in old space as well as in perm space ?. When new space fills up I expect only new gc but not FULL GC. Old space is only 126 MB filled ( out of 194MB) Permspace is only 129MB out of 215 ( max perm space is 256mb) These is our setting -Xms2410m -server -XX:CMSInitiatingOccupancyFraction=75 Xmx2410m -XX:NewSize=512M -XX:MaxNewSize=512M -XX:MaxTenuringThreshold=6 -XX:SurvivorRatio=5 -XX:TargetSurvivorRatio=80 -XX:MaxPermSize=256M -XX:ThreadStackSize=256 -verbose:gc -XX:+PrintGCTimeStamps -XX:+PrintClassHistogram -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSParallelRemarkEnabled -XX:+UseCMSCompactAtFullCollection -XX:CMSFullGCsBeforeCompaction=0 -XX:+HandlePromotionFailure -XX:+UseCMSInitiatingOccupancyOnly -XX:CMSMarkStackSize=32M -XX:CodeCacheMinimumFreeSpace=2M -XX:ReservedCodeCacheSize=64M - -XX:CMSMaxAbortablePrecleanTime=1 -XX:+PrintGCDetails -XX:+PrintHeapAtGC -XX:+PrintTenuringDistribution - 1071256.659: [Full GC {Heap before gc invocations=4293: par new generation total 449408K, used 380965K [0x4f800000, 0x6f800000, 0x6f800000) eden space 374528K, 99% used [0x4f800000, 0x66517448, 0x665c0000) from space 74880K, 9% used [0x665c0000, 0x66cb2318, 0x6aee0000) to space 74880K, 0% used [0x6aee0000, 0x6aee0000, 0x6f800000) concurrent mark-sweep generation total 1943552K, used 141477K [0x6f800000, 0xe6200000, 0xe6400000) concurrent-mark-sweep perm gen total 215832K, used 129513K [0xe6400000, 0xf36c6000, 0xf6400000) 1071256.661: [CMS: 141477K->126065K(1943552K), 3.9483474 secs] 522443K->126065K(2392960K), [CMS Perm : 129513K->129487K(215832K)]Heap after gc invocations=4294: par new generation total 449408K, used 0K [0x4f800000, 0x6f800000, 0x6f800000) eden space 374528K, 0% used [0x4f800000, 0x4f800000, 0x665c0000) from space 74880K, 0% used [0x665c0000, 0x665c0000, 0x6aee0000) to space 74880K, 0% used [0x6aee0000, 0x6aee0000, 0x6f800000) concurrent mark-sweep generation total 1943552K, used 126065K [0x6f800000, 0xe6200000, 0xe6400000) concurrent-mark-sweep perm gen total 215832K, used 129487K [0xe6400000, 0xf36c6000, 0xf6400000) } , 3.9511002 secs] 1071289.014: [Full GC {Heap before gc invocations=4294: par new generation total 449408K, used 129843K [0x4f800000, 0x6f800000, 0x6f800000) eden space 374528K, 34% used [0x4f800000, 0x576ccd88, 0x665c0000) from space 74880K, 0% used [0x665c0000, 0x665c0000, 0x6aee0000) to space 74880K, 0% used [0x6aee0000, 0x6aee0000, 0x6f800000) concurrent mark-sweep generation total 1943552K, used 126065K [0x6f800000, 0xe6200000, 0xe6400000) concurrent-mark-sweep perm gen total 215832K, used 129496K [0xe6400000, 0xf36c6000, 0xf6400000) 1071289.016: [CMS[Unloading class sun.reflect.GeneratedSerializationConstructorAccessor1251] [Unloading class sun.reflect.GeneratedMethodAccessor3111] : 126065K->123793K(1943552K), 4.6073158 secs] 255908K->123793K(2392960K), [CMS Perm : 129496K->129483K(215832K)]Heap after gc invocations=4295: par new generation total 449408K, used 0K [0x4f800000, 0x6f800000, 0x6f800000) eden space 374528K, 0% used [0x4f800000, 0x4f800000, 0x665c0000) from space 74880K, 0% used [0x665c0000, 0x665c0000, 0x6aee0000) to space 74880K, 0% used [0x6aee0000, 0x6aee0000, 0x6f800000) concurrent mark-sweep generation total 1943552K, used 123793K [0x6f800000, 0xe6200000, 0xe6400000) concurrent-mark-sweep perm gen total 215832K, used 129483K [0xe6400000, 0xf36c6000, 0xf6400000) } , 4.6100803 secs]

Re: Strange long ParNew collections
by Y.S.Ramakrishna＠Sun.COM 19 May '09

Yes, from your description, it's very likely you are running into the bug that was fixed in CR 6786503. The fix is available in 1.5u19 (and 6u14 and open jdk 7). Your Sun support can confirm that this is indeed the bug if you send them a series of pstacks taken during the "hang" (i suppose you would need to have your watchdog get the gcore/pstack before restarting the prcoess since the onset of the bug is somewhat unpredictable and you can't be waiting for the event before your watchdog restarts the process; or you can turn off your watchdog if in a test environment and collect the pstacks manually, since the "hang" usually lasts for a while, even if you have gone out for a cup of coffee :-). -- ramki On 05/19/09 04:27, Kaj Nygren wrote: > Hi, > > Thanks for your help.
