CIsco 6942 'Hangs' and becomes unresponsive

Hello,

We have a customer which is using about 100 Cisco phones (6941). These phones do not use anything else then hunt and pickup groups. The sales department (and a couple of other phone users) are reporting that their phone gets stuck. This means that the 'line'-button light keeps flashing red. The phone does not respond to anything you do. The screen shows the normal idle screen. The PC behind the phone keeps working. The only way to get the phone working again is to replug the network cable.

These people have been working with the phones for about 2 years without problems. We have not changed anything in the configuration (as far as I know..) and now suddenly the problems start occuring. It involves about 15 people / phones who are reporting problems.

Any thoughts?

Regards,

Bryan

HI,

I think your apache tomcat service is utilising lots of memory. And that may be cause of it.

Restart the server will be good option. Is it production environement, if yes raise tac case before doing it.

Re: CIsco 6942 'Hangs' and becomes unresponsive

Hi Ronak,

We are running CUCM 8.0.3 with the default 6941 firmware (not sure which phone firmware). I tried logging into CUCM to retrieve the phone firmware version but I get the welcome screen and then it doesn't continue loading after I click on "continue to this website...".

I tried logging in via CLI but get the following:

The users also report that the phone book is not working. I think this is all related.

Shall I give the CUCM server a reset via power shutdown?

Regards,

Bryan

ps. I left the SSH session open while typing this message. After about 10 minutes I got the command line to work so I'll give it a clean restart tonight.
