OutOfMemory due to high number of snapshots installed in Process Server

How it started.

one of our Process Server farm was crashing after generating lots of heap dumps. CPU usage was almost 100% continuously and AppTarget Node ran out of heap. This is for 7.5.1.0 version.

Investigation
Using the IBM Heap Analyzer tool, we observed that we had a single instance of  com.lombardisoftware.server.ejb.persistence.versioning.BranchManager worth of 4GB+

After some digging we found below iFix.
