Pervasive Monitor Shows Client # 207 no active files

Does anyone know what creates a user in Pervasive 8.6 with a rather strange user id?  The monitor shows Client #207 and then it picks another number like 134.  Each time it appears to not have any files open but it has caused locked files.  It appears to be random.  Have checked to see if there is a workgroup engine that is causing this problem.  Any ideas would be appreciated.

If you are running a Workgroup Engine (WGE), then there is no operating system security support, so EVERY user shows up as "Client #...".  However, since this would be "normal" operation, I suspect that you have a Client/Server Engine (CSE) instead.

The CSE requires the client to authenticate to the server OS (via a named pipe call for Windows servers, or by passing the user name when opening files for a NetWare server).  When this is done properly, the session will show the username in the Monitor screen, and with any DTIO applications, such as our own PSConfig (www.goldstarsoftware.com/psconfig.asp).   If the engine does NOT have a valid authentication token, then it will display the "Client #..." user id as a default.  

So, what can cause this?  It could be an internal process inside the server, such as a replication process (i.e. DataExchange).  It could be a user connection that was only partially cleaned up, or a connection that was only partially created.  Or, it could be a bug in the engine itself.  I can say that these are fairly rare in current versions, and there was an issue fixed over the last few years whereby connections got "lost" somehow.

My first recommendation would be to consider upgrading the system to Pervasive.SQL V8.7.  Also known as Service Pack 3, this free update is available by contacting Pervasive Software and providing your software serial number.  Get info on how to do this from Pervasive's web site at www.pervasive.com/support/updates.  Then, see if the problem recurs.  If it does not, then it's a cheap & easy fix.  

If it DOES come back, then you may need to do a bit more research.  Can you see the sessions in both the Active Files AND Active Users screens?  Are there any files open?  What network address is it attributed to?  What happens if you kill off the odd sessions?  All these things will all help pin it down.
