CCTlgServer.exe only working in one of two servers

I noticed that the Tag logging service {CCTlgServer.exe} is working only in one of the two servers (in Server 2 only). What could be the issue that the tag logging is working in one server and not in the other one? A few points to note: PCS7 V9.1 & WinCC V7.5 + SP2 + Updt 9 The CPUs have high load for both servers Archive segments are around 1000 for both servers Regards. ------------------------------------------------------------------------------------------ Split from CCTlg Server.

If the CPU usage on Server 1 is very high, it might be preventing the `CCTlgServer.exe` service from starting or running properly. Possible solution: Check Task Manager or Performance Monitor on Server 1 and Server 2 to see if the CPU load is causing issues. If the CPU usage is consistently high, consider optimizing the system by: Archiving old tag datato reduce the number of archive segments. Increasing the virtual memory(paging file size) or physical memory. Reviewing script execution, alarms, and other WinCC processes to optimize performance.
