<font face="Arial">Hi guys, I have started having this problem a few
weeks ago and it happens about once a week after which I have to
restart my Twisted based server to function again. It seems to be
happening when I make RPC calls using twisted.web.xmlrpc.Proxy. I have
reason to believe that I am either running out of file handles or
connection limits. I have up-sized my connection limits and ulimit -n
gives me 9000.<br>
<br>
I receive less than 30 connections though so there must be some kind of
leak. The error I'm getting is the following:<br>
<font face="Courier New, Courier, monospace"><br>
Unhandled Error<br>
Traceback (most recent call last):<br>

exceptions.ValueError: filedescriptor out of range in select()</font><br>
<br>
<br>
Now I know this is a very generic error and it could mean a lot of
things, but how would I even start tracking the leak down? Is there a
way I can try and track the number of file descriptors?<br>
<br>
I am using Twisted version 8.2.0 on Ubuntu Server Edition 9.10<br>
