We are using Pervasive 8.5 and, with some new techies looking at our server, have noticed what appears to be a memory leak in the Pervasive ntdbsmgr process.  The amount of memory use builds and builds all day long, and usually goes back down when all are logged off of Evo, but sometimes, randomly, it does not and eventually the server locks and needs a restart.  I don't know if this is a pervasive problem that would be fixed with the 8.7 update, or if it is something with my Windows 2000 server.  I did not pinpoint it to this in the past but every now and then everyone is locked out of Evo and I have to restart the server, so I wonder now if this is the reason.
Has anyone experienced this or know what is going on here and how to fix it?
