In the VMXL Activity Log, I'm getting the error
"Warning, A session has timed out after 1 minutes. This is most likely caused by a start of call class or action element at the top of the callflow not completing before the voice browser's fetch timeout occurred. To resolve it ensure this class executes in a timely manner or run it in the background. Session timeouts may also occur under high load or if there are issues with a load balancer or voice browser."
 
What is happening to the call is I'm hearing silence for about 30-40 seconds and then the call fails and is routed to my default error path, which is just an external recording/VM.
 
 
The funny thing to me is the application "ChkHours" we are using is used across several Line of Business with over 70+ locations, i.e. ingress points.  So why are we not having this issue at any of the other locations?  Also, I don't know what is affected if I were to increase the timeout.  My guess is the call would just hang and I'd get the same result but instead of "1 minutes" it would say "30 minutes" 

 
Is this a voice enabled application?  I currently am experiencing something similiar and we've narrowed it down to the MRCP Client / VXML parser integration on the gateway.  Is this one location running a different IOS?   I don't think that increasing the timeout would not help you here...  it seems the gateway is killing the media and leaving the session with vxml server open.  I'm still working our TAC case for a solution. I'll provide an update if we find something definitive.

Change the session timeout from 1 to atleast 5 mins. 1 minute timeout will not work well and you may get this error often. Also after increasing the timeout the call may not hang if there is no issue. If there is a issue somewhere with your code or elsewhere, you could see this issue.
Try with 5 mins and let me know if the error persists.

I have had a plain simple app in CVP 8.5 that would timeout. All it would do is loaded some data into session and it would timeout if the session timeout was set to 1 min. Again that was random.
I would say that set it to at least 3 mins and if it is still happening, it probably indicates a issue with code or startup class. Setting to 1 min is inviting trouble and may not always necessarily indicate a code or script  issue.

Janine Graves has created a new message in the forum "CVP - All Versions":

--------------------------------------------------------------
Can you confirm that you are executing a Start of Call java class? And
if so, is it running in foreground or background? (Project
Properties/Call Studio/Endpoint Settings)

Are you trying to execute a Subdialog Invoke at the beginning of the
application?

Just wondering.

This is not a voice enabled application.  Also, this is not running a different IOS than the other sites the gateways are all 15.1

I'm with you on the increased timeout not being the solution in this case.  I'll be very curious to see the results of your TAC case.  And once my case gets resolved I'll post my results as well.
