I have a performance issue where the application cannot execute a DB query when a particular page is accessed and the page fails to load. The stack trace for the error is as follows:
Caused by: java.rmi.UnmarshalException: Error unmarshaling return; nested exception is:

This issue is observed when the DB size is growing rapidly (approx. 3GB a day). Any suggestions on how to prevent this or fix this would be really appreciated.
