Possible memory leak in Openfire 3.10.2

We've recently migrated & upgraded Openfire.  The new server is a SLES 12 machine, with Openfire installed with the RPM.  Database is MS SQL.  We usually have about 60 users on at a given time.

We use 4 plugins:

1. Broadcast
2. Client Control
3. Monitoring Service
4. Search

I'm seeing an odd memory behavior that wasn't present on our 3.9.x install.  Java memory will rapidly climb to around 150mb, before dropping to around 35mb.  Has anyone else out there experienced this?

Best regards,

Rob
