Unanswered Question

Can someone please inform me how low the memory can be before I would experience problems with phones disconnecting or other issues?

Thank you,

Rose

I have this problem too.

sorry I forgot to enter that information. We're running CM 4.1(3) on a (7815SE1) Windows 2000 Server version 5.0.2195 sp4.

Thanks!

usually if CPU or memory are sustained above 80% or show spikes it can cause issues

that's a small server so we can take it a little lower, around 70 for a small server

I have noticed that this server has gone as low as 11.4mb of free memory without any known impact and cpu only reaches 100% for a brief second. However, I have received messages in the event viewer stating,

"The Cisco CallManager service terminated unexpectedly. It has done this 1 time(s). The following corrective action will be taken in 60000 milliseconds: Restart the service.

I'm trying to pinpoint the actual cause. I would also like to set a monitor on the memory as to how low it can go before alerting for a service impacting issue. Thanks again!

i'd open a TAC case using the high memory/CPU keyword so they can look at drwatson logs. also depends on how many phones and users you have there, that server has the smallest capacity of them all

I tried that but I'll open a new one to see if I can get someone else. Thanks again for all your help.
