<div>Hi all,</div>
<div><br></div>
<div>I am trying to stream for over 1k users on Ubuntu 16.04. I
notice that when stream connection is over 1024, it get warning
like this:</div>
<div><br></div>
WARN connection/_accept_connection accept() failed with error 24:
Too many open files<br>
<div><br></div>
<div>Tried these configs and reboot, it won't work!</div>
<div>
<div>/etc/pam.d/common-session</div>
<div>session required pam_limits.so</div>
<div><br></div>
<div>/etc/sysctl.conf</div>
<div>fs.file-max = 100000</div>
<div><br></div>
<div>/etc/icecast2/icecast.xml<br></div>
<div><clients>20000</clients></div>
<div><br></div>
<div># open file limit</div>
<div>/etc/security/limits.conf</div>
<div>icecast2 hard nofile 90000</div>
<div>icecast2 soft nofile 50000</div>
<div>icecast2 hard nproc 90000</div>
<div>icecast2 soft nproc 50000</div>
</div>
<div><br></div>
<div>How do I know?</div>
<div>ps aux | grep icecast2</div>
<div>cat /proc/ICECAST2_PID/limits</div>
<div>max open file is still 1024</div>
<div><br></div>
<div>In the end, I have to add the following line to
/etc/init.d/icecast2</div>
<div>
<div><br></div>
<div>ulimit -n 20000</div>
</div>
<div><br></div>
<div>And I can stream over 1k users now. There is no config about
ulimit for icecast2, and therefore, I suggest that we add something
like this in /etc/init.d/icecast2</div>
<div><br></div>
<div>
<div># Check if the ULIMIT is set in /etc/default/icecast2</div>
<div>if [ -n "$ULIMIT" ]; then</div>
<div> # Set the ulimits</div>
<div> ulimit $ULIMIT</div>
<div>fi</div>
</div>
<div><br></div>
<div>And add a /etc/default/icecast2 with the following sample
config</div>
<div><br></div>
<div>
<div># Example: ULIMIT="-n 4096"</div>
<div>#ULIMIT="-n 4096"</div>
</div>
<div><br></div>
<div>I steal these from Nginx config! Anyway, what I am saying is
that we need a config file to deal with this issue!</div>
