I am in the middle of upgrade from ZCM 11 SP1a to SP3. As first step, I yesterday upgraded the server to 11.2.4. After that, a problem appeared. Approximately every 4 hours the dbsrv12 process jumps to 100% CPU and remains there for 80 minutes. I've been looking at loader-messages.log, services-messages.log and output of 'zman ql', but cannot see anything obvious there. How can I find out what exactly the database is doing during these high utilization periods? As the problem appears with quite regular 4 hour intervals, it looks like some scheduled task, but I can't think of any obvious place where to look for one.
