Hello,<br><br>On a production system, I'm seeing this:<br>
[Feb 13 16:47:00] WARNING[14742] res_agi.c: Unable to create toast pipe: Too many open files<br>
[Feb 13 16:47:00] WARNING[9283] acl.c: Cannot create socket<br>

[Feb 13 16:47:00] ERROR[14732] rtp.c: Unable to allocate socket: Too many open files<br><br><br>Typing ulimit -a, shows :<br>
# ulimit -a<br>
core file size (blocks, -c) 0<br>
data seg size (kbytes, -d) unlimited<br>
scheduling priority (-e) 0<br>
file size (blocks, -f) unlimited<br>
pending signals (-i) 16382<br>
max locked memory (kbytes, -l) 64<br>
max memory size (kbytes, -m) unlimited<br>
open files (-n) 1024<br>
pipe size (512 bytes, -p) 8<br>
POSIX message queues (bytes, -q) 819200<br>

My main source is <a href="http://ss64.com/bash/ulimit.html" target="_blank">http://ss64.com/bash/ulimit.html</a><br>and I also found this <a href="http://lists.digium.com/pipermail/asterisk-dev/2006-October/024091.html" target="_blank">http://lists.digium.com/pipermail/asterisk-dev/2006-October/024091.html</a> where I could read <br>
<pre>><i> And what does 'ulimit -n' say for your Asterisk process?</i></pre><br><br>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 ?<br>
</blockquote><div>Finally, it seems this command is enough :<br>su asterisk --shell /bin/sh --command "ulimit -n"<br> </div><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
2. Is there an easy and safe way to increase the number of files opened by asterisk ?<br></blockquote><div>Replace the question above by this one<br> "Is there an easy and safe way to artificially increase the number of files opened by asterisk ?"<br>
