[AG-TECH] Connection Interrupted?

[Todd Zimmerman]

Hi All,

We've been getting a message box intermittantly on our main node that says:

"Your connection to the venue is interrupted and you will be removed from the
venue. Please, try to connect again." 

After clicking "OK" I can enter the venue again, and all is well.

We're running AG 2.1.1 with Win2k on the Display machine and RH7.2 on the
capture machine; however, this issue also occured using AG 2.0.  I'm not sure
how to reproduce it... it just seems to happen after a few hours of being in
a particular venue.  

The offending section of the venueclient.log is attached below.

Sorry if this issue has already been discussed - I can't find a reference to
it at Bugzilla or the tech list.  



Thanks for all your help!
