Hello,

The CCM got VM above 90%. I already restarted the Cisco Tomcat, but the issue still happens, some could provide more detail to solve my problem. I will appreciate any help.

Virtual Memory 90%

Marcos,

1. What is the complete CUCM version & hardware model used ?

2. Is it for lab or production purpose ?

3. Did you use OVA file while installing the CUCM or the resources were allocated manually ? If manually, could you detail the allocation ?

Virtual Memory 90%

MC,

Thanks for the details. Pls ignore my 3rd question as I thought it's Virtualized CUCM.

Do you mean, you see this high memory usage even after rebooting the server ? If not, could you check if the reboot helps lowering it down ? Appears like a memory leak issue.

Virtual Memory 90%

Hi GP,

I reseted the server, and the virtual memory goes down to 70%. After 4 days the VM is increasead to 82%. I Read that the version of CCM 7.1.5.33900-10 has a bug. Do you know about anything about this issue. Could you provide any information about how solve this problem?

Thanks a lot!

Virtual Memory 90%

Hi Marcos,

                   Usually when this occurs, it is always preferred to take a look at the process which is eating up all the memory resource.

use the below commands to  get an idea which process it is.

i)  show process using-most memory

ii)  show process load memory

iii) show status

iv) show hardware

Most often than not "Cisco Tomcat Service"  is the culprit. if you see that  then restart that particular service and it will solve the issue. you can collect the logs "Tomcat catalina.out" from RTMT to confirm this. (Usually its the TAC or the BU who does this job as they can read the logs well ))

One of the example is

http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCtj50884

Also sometimes Rogue registration attempts cause CUCM high Virtual Memory and Core dumps. For which you can collect the Event-viewer application log/ Event viewer system log and  from RTMT tool to know the ip addresses of the devices which are causing this.

So it will be clearer from the logs as to what is it that is causing this issue

hope this helps.

Abdul
