You can use Memory Analyzer Tool (MAT) to check if your problem is caused by a programming issue in your code. If it's a such case, then this issue should be identified and fixed. The faster way for a temporary fix is to increase the heap size (-Xms and -Xmx parameters). But if the root cause is a problem with your code (which causes memory leak), then the memory will be filled over time anyway.

Best Regards,

Dear Ramu Mohan,

As Andrzej mentioned increasing the heap can be a solution.

To be able to find out the exact cause of the error we would need to check the leak suspect report.
Please also go through the following SAP note, which is about how to deal with OOM errors:
1289240 - How to deal with out of memory errors

All the bests,
