SpeedTest often fails with "java.lang.OutOfMemoryError: GC overhead limit exceeded" ----------------------------------------------------------------------------------- Key: DROOLS-2485 URL: https://issues.jboss.org/browse/DROOLS-2485 Project: Drools Issue Type: Task Components: decision tables Affects Versions: 7.8.0.Final Reporter: Jan Hrcek Assignee: Toni Rikkola Priority: Minor Labels: verifier Attachments: drools-wb_run1.png, drools-wb_run2.png - when I run just that test class locally from IntelliJ, it runs ~20 seconds, with small Metaspace/heap consumption - on jenkins (there's maven module-level build parallelism with -T2), it runs 110-180s - no idea why it runs so much slower. - I tried several time running identical command as is running on jenkins [2], including version of JDK and memory settings == xmx=2G: - the Heap/Metaspace usage didn't get near the 2G maximum (see screenshots from VisualVM from 2 runs) - the running time of that SpeedTest was 40-80s - slaves used for full downstream build have 24G RAM + 8G swap, so lack of RAM shouldn't be an issue - there seems to be no connection to the issue you mentioned [3] - looking at history of this SpeedTest I see that you committed it initially as @Ignore, but Jozef later un-ignored it. Since this can be considered performance test and is failing randomly from time to time, I think we should mark it with @Ignore again.
