JVM Crashing very frequently
We have a situation where the JVM is crashing very frequently. Attaching the err pid file that is generated.
We are using Pega 7.2.2 on tomcat.

hi Ajay,
We are making the changes and trying . Meanwhile can you please let me how we arrived at a conclusion that it is a memory utilization issue?
Thanks,

We observed that we were using tomcat version 7.0.39. There was a critical bug fixed in 7.0.40 as per https://bz.apache.org/bugzilla/show_bug.cgi?id=54756
Once we updated to version 7.0.75 we stopped seeing the issue. I guess this should be documented in the pega support guide
Hi Binod,
Is this a production system? I can see that you are running with a total of 4 CPU on a 64bit OS architecture with a 32GB memory. The following JVM arguments are being used:
jvm_args: -Xms128m -Xmx4096m -XX:MaxPermSize=1024m
You can use the following arguments and see if this works for you
-server -Xms2048m -Xmx4096m -Xmn1024m -XX:MaxPermSize=1024m -XX:+UseParallelGC
If you still have issue you will need to monitor your memory usage to check if you don't have any leaks or some process requesting too much new object while the memory usage is already high.
