Hello, Thank you for the reply. I checked the parent of the zombie processes, and they seem to be "SIP receiver" processes as per the following "ps -ef" extract and "opensipsctl fifo ps" information. We're not running the "respawn" patch.
Any more advice very welcome, thanks again! user 5830 1 0 06:38 ? 00:00:00 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5832 5830 0 06:38 ? 00:00:16 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5833 5830 0 06:38 ? 00:00:16 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5834 5830 0 06:38 ? 00:00:16 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5835 5830 0 06:38 ? 00:00:16 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5836 5830 0 06:38 ? 00:00:16 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5837 5830 0 06:38 ? 00:00:16 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5838 5830 0 06:38 ? 00:00:16 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5839 5830 0 06:38 ? 00:00:16 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5840 5830 0 06:38 ? 00:00:01 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5841 5830 0 06:38 ? 00:00:00 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5842 5830 0 06:38 ? 00:00:00 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5843 5830 0 06:38 ? 00:00:00 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5844 5830 0 06:38 ? 00:00:00 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5845 5830 0 06:38 ? 00:00:00 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5846 5830 0 06:38 ? 00:00:00 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5847 5830 0 06:38 ? 00:00:00 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5848 5830 0 06:38 ? 00:00:00 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5849 5830 0 06:38 ? 00:00:00 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5850 5830 0 06:38 ? 00:00:00 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 5851 5830 0 06:38 ? 00:00:00 /sbin/opensips -m 256 -P /var/run/user/opensips.pid user 7260 5833 0 08:30 ? 00:00:00 [opensips] <defunct> user 7261 5833 0 08:30 ? 00:00:00 [opensips] <defunct> user 7262 5833 0 08:30 ? 00:00:00 [opensips] <defunct> user 7263 5833 0 08:30 ? 00:00:00 [opensips] <defunct> user 7264 5833 0 08:30 ? 00:00:00 [opensips] <defunct> user 7265 5833 0 08:30 ? 00:00:00 [opensips] <defunct> user 9770 5835 0 08:37 ? 00:00:00 [opensips] <defunct> user 9771 5835 0 08:37 ? 00:00:00 [opensips] <defunct> user 9772 5835 0 08:37 ? 00:00:00 [opensips] <defunct> user 9838 5834 0 08:38 ? 00:00:00 [opensips] <defunct> user 9839 5834 0 08:38 ? 00:00:00 [opensips] <defunct> user 15519 5833 0 08:57 ? 00:00:00 [opensips] <defunct> user 15520 5833 0 08:57 ? 00:00:00 [opensips] <defunct> user 15521 5833 0 08:57 ? 00:00:00 [opensips] <defunct> user 15522 5833 0 08:57 ? 00:00:00 [opensips] <defunct> [r...@hostname ~]# opensipsctl fifo ps Process:: ID=0 PID=5830 Type=attendant Process:: ID=1 PID=5832 Type=SIP receiver udp:xxx.xxx.xxx.xxx:5060 Process:: ID=2 PID=5833 Type=SIP receiver udp:xxx.xxx.xxx.xxx:5060 Process:: ID=3 PID=5834 Type=SIP receiver udp:xxx.xxx.xxx.xxx:5060 Process:: ID=4 PID=5835 Type=SIP receiver udp:xxx.xxx.xxx.xxx:5060 Process:: ID=5 PID=5836 Type=SIP receiver udp:xxx.xxx.xxx.xxx:5060 Process:: ID=6 PID=5837 Type=SIP receiver udp:xxx.xxx.xxx.xxx:5060 Process:: ID=7 PID=5838 Type=SIP receiver udp:xxx.xxx.xxx.xxx:5060 Process:: ID=8 PID=5839 Type=SIP receiver udp:xxx.xxx.xxx.xxx:5060 Process:: ID=9 PID=5840 Type=timer Process:: ID=10 PID=5841 Type=timer Process:: ID=11 PID=5842 Type=MI FIFO Process:: ID=12 PID=5843 Type=TCP receiver Process:: ID=13 PID=5844 Type=TCP receiver Process:: ID=14 PID=5845 Type=TCP receiver Process:: ID=15 PID=5846 Type=TCP receiver Process:: ID=16 PID=5847 Type=TCP receiver Process:: ID=17 PID=5848 Type=TCP receiver Process:: ID=18 PID=5849 Type=TCP receiver Process:: ID=19 PID=5850 Type=TCP receiver Process:: ID=20 PID=5851 Type=TCP main On Mon, Apr 26, 2010 at 12:22 PM, Bogdan-Andrei Iancu <bog...@voice-system.ro> wrote: > Hi David, > > Let's try and see what's the parent process of the zombie procs -> check > with ps and correlate (for the name) with "opensipsctl fifo ps" > > I guess the parent of the zombies should be the "attendant proc" .
