too slow sql's
From time to time I can not run sql's on the database, meaning that if normal they are runing for a few minutes now I have to wait few hours to get results.
This happens once at the begining of January and second time at the begining of march.
Looking on UDUMP I sow in the trace files the error:
opitsk: network error occurred while two-task server trying tosend break; error code = 12571
After two days the situation was coming back to the normal.
I could not find an explanation.
Please could you help me?
Thanks,
Carmen
