System starvation

[adinapoli]

Hi,

after the upgrade from OS 2000.2.7sr8 to 2000.4.3a of a CCM publisher, some Cisco Call Manager services on this server (RIS data collector, CTI Manager e Call Manager) don't start because of a lack of CPU resources. The upgrade was ok, also the phase 3 was ok and all the update were installed correctly. It seemms that a service called System in the task manager take all the CPU resources.

Anyone knows what I have to do?

Thanks in advance

Antonio

From Microsoft:

Your Windows 2000-based computer stops responding, you cannot log on to Windows, or your CPU usage for the System process approaches 100 percent

I have applied the hotfix but it doesn't work.

The symptoms are similar to the ones described in the kb841382 (I haven't the files listed there) and in the forum.

I notice that:

1) the CPU usage of the System process is between 80% and 95% for about 55 minutes - 1 hour, then the CPU usage becomes normal

2) The services that dont't start are

- Ris Data Collector (sometimes it starts)

- CTI Manager (few times it starts, many times there is a popup alert with an error)

- Call Manager (it never starts)

After 1 hour I often try to restart Call Manager and it works only for 25 minutes, then there is a "strange" lack of resources.

The lack of resources is so tremendous that I can't open "Event viewer" or "Services" and I always need to shut down Windows.
