Collaborator Server 14.0.14001 excessive memory usage

My Collaborator server instance seems like it's got a memory leak.     

It was consuming 10 gigs of ram.  Our peak usage in the last 30 days has been 6 users, probably not more than 3 or 4 simultaneously.

After a restart, the Collaborator server process is sitting around 2 gigs of ram.

1) Is this expected/typical memory usage?

2) Is there a way to set a "max memory usage" parameter for the Collaborator server process?
