We have recently been getting some error messages from the CUCM server.
Available virtual memory below 30 Percent. tomcat (972 MB) uses most of the memory

We were informed from Cisco TAC that this is still within normal operational parameters so nothing to worry about. The cause maybe due to the length of time the servers have been up and running and when we looked into that we found that CUCM 2 (the server that talks to all of the phones) had been running for 497 days. CUCM 1 (the server we make changes through) has been up for 432 days. The technician we were dealing with on the TAC case said it is recommended to restart the servers every 100 to 150 days. Something we can do every semester.

The restart will be done during the Maintenance window Thursday May 26 (5:00 to 7:00 am)

We will restart CUCM 1 first, this will have no impact on the phones, once that server is back up and running we will restart CUCM 2. When we restart CUCM 2 all of the phones will switch over to CUCM 1, this will cause the phones to reset and may take a minute for the reconfiguration to complete.
