While running a load test on the Speech Server, if the TAH worker process is set to recycle at a certain time (say 2 AM, the default), I see an error from the speech server with Event ID 26119
The error message says: The main service detected that a TAH worker process (PID 2696) has terminated unexpectedly. Any sessions that were in progress have been aborted.
This causes the client side application to get stuck in a bad state. This is the last issue remaining for our load test run. We want to show that even during a recycle, the system may lose a couple of calls but it will not cause the system to stop working completely.
Note, sometimes when the recycle happens, the error does not occur and everything runs smoothly. When the error does occur, the client side goes down, even though the speech server recovers by starting a new TAH server process.
Any help in eliminating the error is much appreciated.
