Hello everyone, Recently, I had one of the JVMs going into this weird state wherein minor gc start kicking almost every minute but what is most surprising that it is one minor GC is taking as much as 100 seconds. The heap size is around 12 gigs and young gen is about 30% of that. As soon as gc starts, understandably CPU usage started increasing as well. I am not able to figure out how would one minor GC take this much time. The machine does not have swapping enabled. I also ran sar and confirmed there was no swapping during the issue. We are using parallel GC for young gen and CMS for old gen GC. How can I go about troubleshooting this further? Any pointers will be appreciated.
