When I installed FDS the setup script was pretty specific about the need to ncrease the max number <br>
of open file descriptors.<br>
<br>
This is what I setup:<br>
<br>fs.file-max 64000<br>
in /etc/sysctl.conf<br>
<br>
* - nofile 8192<br>
in /etc/security/limits.conf<br>
<br>
and in my init.d script:<br>
ulimit -n 8192 <br>
<br>
