The System Center Configuration Manager (SCCM) server performance degrades and will eventually encounter system lockup when the OfficeScan Real-time scan is enabled. The system lockup can occur for a few minutes or up to a couple of hours. During the system slow down, there would be no indication of High CPU or memory utilization by any particular system process.
An early sign of the problem may occur when there are large amount of *.RPL and *.TRS files created under D:\Microsoft Configuration Manager\inboxes\. These location and files help provide information for site to site replication information or updates. These files are supposed to be created/deleted on a normal basis by SCCM.
To resolve this issue:
- Go to the OfficeScan server that is managing the client and browse the location where the OfficeScan server was installed.
By default, it is \Program Files\Trend Micro\OfficeScan\PCCSRV.
- Open and edit the ofcscan.ini file.
- Look for the following parameter:
- Set the value of the parameter to "1".
For OSCE 11.0 and XG, the default value is "-1". For other OSCE versions, the default value is "0".
- Save and close the file.
- Log on to the OfficeScan server management console.
- Go to the Global Client Settings and click Save.
- Go to the affected client(s) and verify that the following registry value is set:
Always back up the whole registry before making any modifications. Incorrect changes to the registry can cause serious system problems.
REG_DWORD: DisableCtProcCheck = 1
The above ofcscan.ini file will push this registry change to all the managed clients.
