Dear experts,

Please help me with the following problem. I have a redundant pair of servers with PCS7 v8.2. One of the servers is broken. The other one that still operates is having an issue with CCTlg Server running at 87% of computer processor capacity. This server has two operating stations that are connected on it. 

Question:

How can I get the CCTlg Server to run at normal usage of computer processor capacity without disturbing the process and not loose the connection with the stations.

Thank you!

Best regards!

Hello Daos,

the process "CCTlgServer.exe" is the Taglogging Server, which
delivers the data from the Taglogging Archives for other
processes, i.e. the TrendControl in the Graphics Runtime.
It is not clear, why it has such a high CPU load.
How have you configured the Taglogging Archives.
Have you a high number (>200) archivesegments ?

see FAQ:
"How many single segments can be connected to the SQL server in PCS 7
without impairing performance?"

Hi bg2492,

The system was configured so that it generates more that 1100 small segments over a 3 year interval (one segment each day of around 40 MB). Now it's all clear for me. Thank you very much for your help.

Daos.
