[OpenSIPS-Devel] potential timer shifting

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).
