file http://box.tutpro.com/tmp/gdb_kamailio_20131223_145323 contains gdb bt of all presence server processes when presence server is not responding to any new requests. looks like several processes are in futexlock.h if that tells something.
this is with kamailio 4.0.
actually, looks like it was with an older version of kamailio. will upgrade and see if hangup happens again.
