Orion NCM causing 100% CPU Utilization

Question

Hello,

We currently have Orion NPM and NCM running concurrently on the same server. A colleague who has recently left set this up and I've been tasked with managing it now so still finding my way round. The problem is that NCM keeps using 100% of the CPU which in turn, prevents NPM running. The only way I can get it working again is by killing of the ConfigAutoDownload.exe and ConfigMgmtJob.exe processes. I've updated the NCM version to v5.1 as I read it was a known bug but this has not resolved the issue.

We're monitoring around 600 nodes with a nightly config backup and weekly inventory running only. Additionally realtime config changes are updated. Nothing else is scheduled, yet every day the system seems to generate a number of syslog jobs at varied times of the day. I can find where these jobs are initiated from, each one is a config backup of a device.

The server is has a 2.66GHz Xeon CPU with 2GB of RAM (about to make this 4GB)

Running server 2003 R2 SP1

Any help would be greatly appreciated.

For those experiencing this CPU at 100% issue, please ensure that you have a support case open so we can continue to track this properly.

I am also experiencing a problem with config download jobs pegging the server cpu.  In my case, the problem seems to be related to using SNMP to retrieve the configs from the devices.  If I configure NCM to use telnet to download the configs then the jobs seem to run fine.

We are also seeing this. I have created a support case #89950.

But we are not using Real time Change Detection. Every time we start a download of configs from more than 10-15 devices, the CPU goes 100%, and the machine stops responding. We can't even access the machine from the console, so the only way to get in to it, is power off!!

Is there any soloution to this ?
