Symptoms
JIRA node was crashing again and again.
The Java process is not running and it was not shut down manually.
Files with names like
hs_err_pidxxxxx.logbeing created in the app server'sbindirectory, containing text such as the below:1 2 3 4 5 6 7 8 9 10 11 12 13 14# An unexpected error has been detected by HotSpot Virtual Machine: # # SIGSEGV (0xb) at pc=0xfe9bb960, pid=xxxxx, tid=xx # # Java VM: Java HotSpot(TM) Server VM (1.5.0_01-b08 mixed mode) # Problematic frame: # V [libjvm.so+0x1bb960] # --------------- T H R E A D --------------- Current thread (0x01a770e0): JavaThread "JiraQuartzScheduler_Worker-1" [_thread_in_vm, id=17] siginfo:si_signo=11, si_errno=0, si_code=1, si_addr=0x00000000
This indicates Java is crashing.
Cause
A Java virtual machine crash is analogous to getting a Windows Blue Screen of Death when using MS Office or a web browser. That said, JVM bugs causing crashes often appear when the JVM is running out of memory. There can be many reasons for JVM crash, please refer to Java Crashes page and follow the suggestions.
For this specific issue where JVM is crashing because of IPv6 lookup following appears in the hs_err_pid*.logcrash log

Set the following parameter on JIRA startup. This JVM parameter would force IPv4 lookup instead of IPv6.

-Djava.net.preferIPv4Stack=trueRestart JIRA
