When there are about 200 sockets, or so, i'm getting errors: "unable to select on socket" We are running multithread application, for each thread there is one socket. TRACEBACK contains: r = self.connection.recv(1024) error: unable to select on socket. This error appeared after fixing this problem: http://sourceforge.net/tracker/index.php?func=detail&aid=1429585&group_id=5470&atid=105470 Python version: 2.5a0 (trunk, Mar 8 2006, 18:28:30) OS version: FreeBSD 6.1-PRERELEASE Soon we will make program that will reproduce this error if needed.

Logged In: YES user_id=33168 What is the value of FD_SETSIZE? Perhaps you should increase this value before including any headers on FreeBSD? If you are using a lot of sockets, you may prefer to use poll() instead of select() as poll() doesn't have the FD_SETSIZE limitation.

Logged In: YES user_id=1449422 Thank you very much! It was fixed by increasing FD_SETSIZE.
