Environment:Jenkins 2.235.3, Using Docker container
Hi,
Since last few weeks we are facing issue with Jenkins master, it crashes every now and then with exception
java.lang.OutOfMemoryError: GC overhead limit exceeded
Below is what we found in logs, attached file "log_trace.txt" contains full exception stack trace.
2020-10-14 15:02:48.604+0000 [id=13455] WARNING h.i.i.InstallUncaughtExceptionHandler#handleException org.apache.commons.jelly.JellyTagException: jar:file:/var/jenkins_home/war/WEB-INF/lib/jenkins-core-2.235.3.jar!/hudson/model/View/index.jelly:42:43: <st:include> org.apache.commons.jelly.JellyTagException: jar:file:/var/jenkins_home/war/WEB-INF/lib/jenkins-core-2.235.3.jar!/lib/hudson/projectViewRow.jelly:35:52: <st:include> java.lang.OutOfMemoryError: GC overhead limit exceeded at org.apache.commons.jelly.impl.TagScript.handleException(TagScript.java:726) at org.apache.commons.jelly.impl.TagScript.run(TagScript.java:281) at org.apache.commons.jelly.impl.ScriptBlock.run(ScriptBlock.java:95) at org.kohsuke.stapler.jelly.CallTagLibScript$1.run(CallTagLibScript.java:99)
When created heap dump and histogram below stack trace is looks suspicious with large size. (attached the full histogram details)
3: 1007784 32249088 java.lang.StackTraceElement
Also attached the GC Root from dump file for same stack trace. We have observed same trace in all our slave dumpExportTable.
Memory parameters configured for Jenkins "-Xmx4096m -XX:MaxPermSize=1024m"
Is this a memory leak causing the failures ? During the same time our CPU usage also clocks as 100%, are they both related to each other ?
Please note this Jenkins instance is running on a dedicated VM.
