Hi Edwin,
According to the logs, the exec of the ul_timer takes considerable time
- if it comes to that, I can provide some patch for more logging to
doublecheck the result.
Once again, the ul_timer is responsible for flushing (periodically) the
registration from mem cache into DB - this operation may put some load
(as I/O and waiting time) on the DB (not necessarily CPU).
