Hi Gao,

Hello,

 

I tried “jstack -m PID”in latest openjdk 8 64-bit and “jhsdb jstack –mixed –pid PID” in latest openjdk 11 64-bit on latest Ubuntu(18.04) and latest fedora (29) and RHEL 8 Beta.

The stack traces returned are always incomplete like following output:

   JavaThread state: _thread_blocked

0x00007f83922526d6  do_futex_wait.constprop.1 + 0x36

 

The issue existed even after I disable the selinux. It can not be reproduced on oracle linux 7.4.

The kernel version on Ubuntu or fedora is 4.15. the kernel version on RHEL 8 Beta is 4.18. the kernel version on Oracle linux 7.4 is 3.1.

I can not find any existed bug for now.

 

 

Is there any clue about this issue?

 

Any reply will be appreciated.

 

Best Regards
