CUCM services down

[Roman Isaiev]

Hello everyone,

Recently on my Subscriber services CallManager and CTI moved to status "Not Running".

Please tell me what logs need to be collected in order to understand what happened.

Perhaps someone will share advice on how to quickly figure out the causes of the problem.

Thank you!

Hi,

>From CLI use 'utils service list' to see what services are running and what
are stopped. Check your DB replication status, check any alert in RTMT such
as disk space full, errors, etc.

Thank you for your reply!

My problem was on 04.06 on Saturday, the alerts have already been erased, is it possible to see the history of the alerts?

[Mohammed al Baqari]

If they aren't dumped to external server, they are overwritten.

Check the output of these commands and share. If you have core file, it
will be helpful.


- utils diagnose test
- show process load cpu sorted
- show status
- utils core active list

I am collected core dump.

I see next message:

0x08498bf1 in IntentionalAbort (reason=0x86ff388 "SDL Router Services declared dead. This may be due to high CPU usage or blocked function. Attempting to restart CTIManager.") at ProcessCTIProcMon.cpp:65

Сould this mean that the problem was caused by the death of the SDL Router Services ?

Does this mean that a failure in the operation of WebDialer caused the service to be disabled?

[Roger Kallberg]

Not very likely. The WebDialer service seems to have reacted that the CTI service was down. A guess would be that the services has crashed due to a defect. This is often of the type that causes a memory leak. Without knowing your exact version of CM it’s very hard to be more specific.

[Roman Isaiev]

Thank you for your reply!

System version: 9.1.2.14900-14

[Roger Kallberg]

I hope that you are aware that your version is out of support since quite some time. As of this you’ll not be able to get support from TAC on your issue.

[Roman Isaiev · Accepted solution]

Sorry for the delay.

Yes, i know that my CUCM EoL, EoS.

This issue was resolved by restarting the servers.

Thank you for your help!
