every hour, at 10 minutes after the hour, the system hangs up for 3-10 minutes. When it frees up the load average for dialog in SM50 is very high. I see in ST02 that CUA swapping is very high also. I cannot seem to track down the culprit. SM37 doesn't show any batch jobs running around that time, nor any that take more than a few seconds. Any help on where to start looking?
Not a BASIS expert.. I've read through SAP Support but can't pin anything down.
