Low Virtual Memory

[tamimicisco]

Hey,

I am facing problem with  "Available virtual memory below configured threshold . Configured low threshold is 30 %
tomcat#1" in CUCM 10.5 .I restarted the Cisco Tomcat service but still showing up  the same error in RTMT.Is it a BUG ?

Thanks

Hi Tamimi,

Do you see the same result after Cisco Tomcat Service. Are you look at same error for old timestamp ?

Check the output from CUCM CLI.

show process load memory

Hi Tamimi,

From the output i dont see tomcat using memory but i see "java" process is using "1194m"  which is not  normal. Can you take a cluster reboot in a MW or kill java process alone see if this VM Alert continous.

How did you fix this problem? I have the same issue after CM 10.5 upgrade restarting the Tomcat didn't fix it before I reboot the cluster want to check with you first.

Thanks.
