Hi all

I had an issue when my end-user do trending SQL data or exporting alarm list, they found the runtime is crash/freeze for Primary Server. The action i do is usually i terminate the Primary server and the Program become normal, but sometime i had an error for this method, the driver cannot communicate and make my program had a lot of alarm.

This issue happen currently happen Friday/Saturday/Sunday morning 1am ~ 4am.

I worry is related to SQL Evacuate which is my ARX file evacuate big data every 1 week.

My historian SQL configuration:

1Hours

1Day

1Week

1Month

Any advice for this issue?

I attach the log file from the server.

Thanks a lot for the answer, i hope found best solution for this.
