What is the nonpaged pool of memory on a CM?

[d.anthony.hadley_2]

Every now and then the Event Logs get an error that says running out of "non paged pool" memory. Recently, a publisher hung and the first error in he sys log was the following. Does anyone know exactly what this is? (meaning a comprehensible explanation, not the one on Microsoft's website) Where do you look when this is being depleted? Any info will be helpful. Thanks. CM ver 3.3.3, no SRs.

Description:

The server was unable to allocate from the system nonpaged pool because the pool was empty.

I believe the non-paged memory pool is basically an amount of memory that is set aside that cannot be dumped out to the pagefile - that is, it is always actually in RAM.

Most references I've seen to this event seem to refer to applications with memory leaks and so on - do you have any non-standard software on your server?

[d.anthony.hadley_2]

No, I just have CallManager on the server. Everything I've seen has referred to memory leaks also. I haven't seen anything on what to do about it.

[Aaron Harrison]

Do you run any AV software on your servers? It could be some piece of malware on your system, or I've seen some references to Symantec AV products causing this errors..

Failing that I suppose the other courses of action would be putting on the latest OS Upgrade/SRs and CallManager SRs.

Tony ,

I had the same problem on a non Cisco CallManager server. Let me know if that is a non Cisco CM .

Jim,

It's a Cisco CallManager. I haven't seen this on any other server. But, several of the Cisco CM servers have this. I'm just trying to get a handle on it.
