I have got a strange problem that I have never seen before on other versions of CallManager.
We have a new installation of CUCM 6.1. It was initially CUCM 6.0 and than, before going live, it was upgraded to 6.1. The installation consists of one Pub and one Sub. The CallManager service is activated on both servers but is running only on the Pub - on the Sub it is shown as Active but Not Running. If I start CallManager service on the Sub manually (from the Serviceability web page) it keeps running for about 30 seconds (it is show as running) and after this time it goes back to Not Running. Any idea what it could be before I open TAC case?
Thanks a lot.
