OK, found the reason. subs_db_mode=3 and notifier_processes=1 (default)
and waitn_time=5 (default) means that NOTIFY requests may be buffered
for 5 seconds.
so when UA quits and sends un-SUBSCRIBE, it will never get the final
NOTIFY, because by that time it has already un-registered itself and sip
proxy produces error message about it. not good at all.
