Hi all,
We have an app running on CUAE 2.4.3 with a patched JTAPI provider (the change to add JtapiCallId). It was working fine, then we started getting these errors:

Restarting the JTAPI service didn't help. All devices are Enabled Stopped. I see the Java process running, so I don't think it's the old "where's Java?" path problem.
This is running against CUCM 6.1.2.1127-1.
Thanks for any help,
Craig

Unfortunately, this is a production CUCM cluster running other applications, so it is not possible to restart the CTI Manager service unless we can communicate to the customer that it will definitely fix the problem. The issue is affecting a production application, so I would greatly appreciate any input you and the team can provide.
Thanks,
Craig

Hi Rajesh,
Yes, I've confirmed the CUCM cluster is marked as 6.1 in CUAE. I sent detailed logs to TAC, please reference TAC #610691521.
Thanks again for any help,
Craig
