Hello, On a production system, I'm seeing this: [Feb 13 16:47:00] WARNING[14742] res_agi.c: Unable to create toast pipe: Too many open files [Feb 13 16:47:00] WARNING[9283] acl.c: Cannot create socket [Feb 13 16:47:00] WARNING[9283] rtp.c: Unable to allocate RTCP socket: Too many open files [Feb 13 16:47:00] WARNING[14732] acl.c: Cannot create socket [Feb 13 16:47:00] WARNING[14732] channel.c: Channel allocation failed: Can't create alert pipe! Try increasing max file descriptors with ulimit -n [Feb 13 16:47:00] WARNING[14732] chan_sip.c: Unable to allocate AST channel structure for SIP channel [Feb 13 16:47:00] WARNING[14732] app_dial.c: Unable to create channel of type 'SIP' (cause 0 - Unknown) [Feb 13 16:47:00] ERROR[14732] rtp.c: Unable to allocate socket: Too many open files
Typing ulimit -a, shows : # ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 16382 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) unlimited virtual memory (kbytes, -v) unlimited file locks (-x) unlimited So it seems that increasing this open files limit from 1024 to 2048 could work around the above issue. Strangely, I can't find much online doc on ulimit and its usage. My main source is http://ss64.com/bash/ulimit.html and I also found this http://lists.digium.com/pipermail/asterisk-dev/2006-October/024091.htmlwhere I could read >* And what does 'ulimit -n' say for your Asterisk process?* 1. How can I specificially read "ulimit -n" for asterisk, for instance when asterisk is run by an asterisk user which has no login or shell ? 2. Is there an easy and safe way to increase the number of files opened by asterisk ? Regards
