Hi, Maybe some of you have encountered this funny error message when starting and even killing kamailio on a Debian 6 with 2.6.x and 3.x kernels and 2.11.3-4: #------------------------- # /usr/sbin/kamailio -f /etc/kamailio/proxy/kamailio.cfg -P /var/run/kamailio/kamailio.proxy.pid -m 4 -M 16 -u kamailio -g kamailio loading modules under /usr/lib/kamailio/modules_k:/usr/lib/kamailio/modules Listening on udp: 127.0.0.1:5062 tcp: 127.0.0.1:5062 Aliases: Message from syslogd@sp2 at Feb 19 11:15:42 ... t of memory [6720] # killall kamailio Message from syslogd@sp2 at Feb 19 11:17:51 ... t of memory [6720] #------------------------- The PID reported here is the kamailio attendant process. It seems to be somehow related to the shared memory. The interesting part about that is that kamailio really starts just fine, and there is plenty (>5GB) of free memory available. It doesn't seem to influence the behaviour of kamailio at all as it's working perfectly fine, so for now it's just annoying, but I'm really curious I've tried to fiddle with mem_join, but it doesn't matter whether it's on or off. Kamailio version is this: # kamailio -V version: kamailio 3.3.2 (x86_64/linux) flags: STATS: Off, USE_IPV6, USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, F_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 4MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled on 19:09:17 Jan 21 2013 with gcc 4.4.5 Has anyone seen this too? What's the cause of that? Andreas
