ViewX Log file abnormal behavior (log files continuously being deleted and created for ACTIVE sessions)

[dtappen]

We are experiencing unusual behavior with the ViewX log files on a Windows Server Terminal Server running MULTIPLE ViewX client sessions (one ViewX instance per RDP client session).  The log files in folder \programdata\schneider electric\clearscada\logs\viewx are continuously being deleted and created for ACTIVE sessions as fast as windows explorer can refresh the contents.  This seems to occur when the number of ViewX instances on the terminal server exceeds 15, though this is not a hard number.

Here is video of this wacky behavior.

That definitely looks pretty crazy.  We have a couple of clients that use RDP to host ViewX and have well over 15 concurrent ViewX sessions, and we're not seeing this behaviour.  Although I don't believe any of them are running exactly this version of GeoSCADA also.

The only advice I'd give is to try to setup an environment with a more recent version of GeoSCADA Expert and see if you still experience the issue.
