Did you ever find the answer to this one? We are experiencing the exact same issue and are also using Trend Micro, so there could be something related. Ours is also a terminal server.

Question
PerfOS error messages on servers
Hi,
All my Windows 2003 servers give the following errors at random intervals.
Event Type: Warning
Event Source: PerfOS
Event Category: None
Event ID: 2012
Date: 6/19/2007
Time: 4:18:39 PM
User: N/A
Computer: SERVER
Description:
Unable to get system process information from system. The status code returned is in the first DWORD in the Data section.
For more information, see Help and Support Center at http://go.microsoft.com/fw
Data:
0000: a1 00 00 c0 ¡..À
Event Type: Error
Event Source: Application Popup
Event Category: None
Event ID: 333
Date: 6/20/2007
Time: 9:50:44 AM
User: N/A
Computer: SERVER
Description:
An I/O operation initiated by the Registry failed unrecoverably. The Registry could not read in, or write out, or flush, one of the files that contain the system's image of the Registry.
For more information, see Help and Support Center at http://go.microsoft.com/fw
Data:
0000: 00 00 00 00 01 00 6c 00 ......l.
0008: 00 00 00 00 4d 01 00 c0 ....M..À
0010: 00 00 00 00 4d 01 00 c0 ....M..À
0018: 00 00 00 00 00 00 00 00 ........
0020: 00 00 00 00 00 00 00 00 ........
When these errors occur, the server is getting unresponsive. RDP sessions are rejected, applications are unable to open on the server stating that insufficient resources exit.
We're running Trend Micro Client/Server/Messaging Suite 3.6. When I stopped the Trend Micro agent on one of the servers, the PerfOS error messages stopped and the server became responsive again, however the Registry I/O errors still remain.
I've checked all the comments on EventID.net, but none of them apply to my situation.
Any ideas?

Ok, I've generated a call at MS. They state it's caused by a memory leak in tmasca. (Antispyware agent from Trend Micro). I've uninstalled all the instances on all servers from the antispyware agent yesterday and we are currently monitoring the servers to see if the problem still occurs. So far so good.

Ok, the problem isn't caused by Trend Micro, but by something else. Can't find it.
