I am recently trying to connect with a venueclient to a venueserver
on the same machine(WinXP, no MC). However both client and server are
blocking once they reached a
specfific part in the process. From the log-files, I can't make up
anything unusual except the fact that I disabled starting of the
Beacon service (see #Bug 1701)
I attached the last parts of my logs from the server and the client
as far as they created output befor entering blocking state.
After that I can only kill the venueclient process through the task
manager and then normally exit the server with ALT-C.
I encountered the same behaviour on a second machine (WinXP, MC) both
times using the latest CVS code of AG3.1 beta-1.
There is no further log-output being created from that point on until
I kill the venueclient.
I hope someone can give me a hint.
Michael,
How long have you waited after the inactivity began? I have noticed
what at first appears to be blocking like you describe but I always
(so far) see some activity within about 30-40 seconds. In fact, this
upper limit has made me wonder whether its connected with the
heartbeat timer. - when looking at the VenueClient debugging output,
the inactivity stops about the time that the next heartbeat occurs.
The delay I'm seeing is not constant; although there is sometimes this
long delay, at other times there is no delay at all.
I've also noticed that this problem affects not just venue entering
but also event distribution for shared applications e.g. reception of
"next page" events in Shared Presentation.
