[Serusers] Weird problem when, restarting ser.

[Jiri Kuthan]

Under normal operation, SER can handle significantly more registrations, by
orders of magnitude. To me, it sounds much more like a result of a memory leak. 
Are you using stock SER or some modified SER? In any case, the way to catch such 
leaks is to set a talkative memory log level (memlog=2 in ser.cfg), recompile ser 
with memory debugging informaiton (uncomment DBG_QM_MALLOC, comment F_MALLOC
in Makefile.defs and do recompile completely) and  watch log output on SER shutdown 
for excessive occurent of unallocated memory fragement. I would be very thankful 
if you could report your observations back to us.
