Hi, In the mean time we have gathered more information on this problem:
As given below, kamailio stops grabbing UDP SIP messages (SIP registrations) after running a while on an embedded ARM and PPC platform (which runs linux 2.6.33 kernel). Some times the hangup occures within hours and some times after couple of days running. NETSTAT OUTPUT: root# netstat -pl | grep kam udp 1047968 0 (null):sip (null):* 8416/kamailio raw 0 0 (null):255 (null):* 255 8416/kamailio unix 2 [ ACC ] STREAM LISTENING 755205 8429/kamailio /tmp/kamailio_ctl Kamailio is started with the following options = -m 4 -n 3 -f <cfg> -D Other relevant info: - When Kamailio hangs, I also noticed that the flag "inuse_transactions" has always the value of '1'. Readout with "kamctl monitor". - A simple cat to /proc/<kamailio_pid>/wchan gives us the function: futex_wait_queue_me. - All possible polling methods are used with -W parameter (sigio_rt, poll, select etc) during these tests. Non of these options did solve this problem. I hope the additional info will clarify more. Thanks in advance.
