About SIPServerTransaction related timers

Hi,

Upon implementing a timer in a JAIN SLEE 1.0 environment (Mobicents),
offered by its TimerFacility, and allowing timer events to be fired to a
custom activity context used uniquely for these timer events, when
running my service I noticed that whenever my timer would be setup I
would get a long list of lines like this:

The service is a Back-to-Back User Agent that responds to network
requests and has an internal TimerFacility timer that is used to
implement a timeout condition that occurs when a custom event from
another application is not received within a given interval.

Well, apparently there is no relationship whatsoever between my SLEE
timer and this SIP timer specific to the nist-sip stack. Naturally the
service uses the SIP RA, but the two things should be quite isolated.
After a few runs my service stops behaving as expected, causing this
glitch to be the closest candidate for trouble..
