Hello,
the bt is from custom timer process, which doesn't handle sip requests
from the network.
Do a 'kamctl ps' and the select one of the sip workers to grab the back
with gdb.
Cheers,
Daniel

once in a while kamailio 4.0 presence server becomes unresponsive, i.e.,
does not process any requests. below is bt full of a process that at
that time takes most of the cpu time. rls_notifier_processes is not
set, i.e., it defaults to 1.
does the bt give any clue why kamailio is unresponsive?
