NBU version is 7.1.0.4 and OS version is Solaris 10.
Issue started 2 days back when server starts hanging all of a sudden. Later got identifed that BPDBM was the one using very high memory.
Here are some outputs from prstat just before it got hung, system got 32GB of RAM
/var/adm/messages :-

If we kill that particular PID, all will come back to normal. But after sometime, another PID will start the same behaviour. All the BPDBM PID will start normally with a normal memory usage. But then one of them will grow in a metter of seconds and start using the whole memory and eventually making the system hang.
issue is running for ast 2 days and Symantec didnt find much from the logs. server is getting hung and keep on getting rebooted after that
