<DIV>I suspect it might be your code. On Twisted 2.5 (with patched epoll bug <A href="http://twistedmatrix.com/trac/ticket/2809">http://twistedmatrix.com/trac/ticket/2809</A> ) we have reactors that run for 3-4 months without restart, that do not consume more than 150MB RSS with 8000+ concurrent connections.<BR></DIV>

I have recently put a simple proxy <BR>server based on Twisted in to production and have been running a live <BR>test on a single host for between 300 and 400 concurrent users. The <BR>server gradually consumes memory to a point where I have to start <BR>thinking about the experience of my users (the server starts <BR>swapping) and restart the process. I
have been watching this <BR>behaviour for the last 10 days and in the meantime have been going <BR>through my code with a fine tooth comb, looking for and testing for <BR>possible memory leaks. I found a few minor ones, but the memory leaks <BR>continue.<BR><BR>Today, out of desperation, I switched the reactor from epoll to <BR>select. Guess what? No more memory leak.<BR><BR>My environment is Linux 2.6, Python 2.5.2, Twisted 8.0.1, twistd. I <BR>was wondering whether anyone could cast any light on this matter? I <BR>am pretty sure that this isn't an issue specific to my code but I <BR>would be interested to hear if anyone else has experienced similar <BR>problems. I would like to be able to switch back to epoll for obvious <BR>reasons, but at the moment, I am not confident in running the Twisted <BR>epoll reactor.<BR><BR>Regards,<BR><BR><BR>Matt<BR><BR> <BR><BR>Matthew
