Hello Prajakta,
Upgrade JVM to latest.
I strongly recommend you to update your JVM. A newer JVM will provide you more consistent runtime behavior, Considerably reduce the usage of the JVM's native memory, enhances memory management and improves debugging capabilities.
SAPJVM 6.1 PL53 is latest i guess.
So please apply the recommendation and let me know the results.
We remain at your disposal for any enquiry.
Have a nice day!
Regards.
Surojit
