[Openroad-users] eClient / App Server crashing

[Martin Pomej]

Hello OpenROAD'ers,
 
OR 4.1 SP3 p11015 running App Server on Windows 2003 and eClients on XP SP2.
 
I'm having a massive head ache at a customer's site with eClient / App
Server and I'm hoping that people out there may have experienced something
similar.
 
Very frequently the following error is occurring, by this I mean it'll
re-occur in approx 10 minutes:
Fatal error: (-101) uc_context_mgr.RestoreContext: Cannot restore session
context.
ContextId 40914 not found.

NB: the ContextId changes each time we encounter the error.
 
The only way to resolve the problem is for the user to restart their pc and
the admin guys to restart App Server. After that's done the very same user
will be able to use the eClient application without any error.
 
Our application is stateful and to me the above error gives the impression
that the eClient is losing it's session with the server and hence falling
over. But the million dollar question, what's causing the eClient to lose
it's session, if that is the problem?????
 
Our client has approx 500 users using the system all through the day, and at
any one point in time they could have roughly 20 concurrent users. 
The server machine has plenty of memory and processing power, and I have
configured 4 name server entries and have left VASA running, as per one of
Durwin's previous emails, so to achieve load balancing.
Should there be only one name server or can anyone suggest any setting(s)
that may improve things?

I'm all out of ideas and the log files are only showing the above session
context error.

If it was a particular component I could reproduce the problem and tackle
things that way, but that's not proving to be the case.
 
Any help would be very much appreciated and may save a dent or two in what
is already my very rough head.
 
Many thanks and merry Christmas to all.
 
Regards, 
Martin Pomej
