Best regards, Alexander. ---------------------------------------------------------------------- >Comment By: Neal Norwitz (nnorwitz) Date: 2006-02-11 22:54 Message: Logged In: YES user_id=33168 Can you build python from source? You can try checking out the current 2.4 SVN. This problem may have been fixed recently. I'm guessing that the socket descriptor value is larger than FD_SETSIZE (probably 1k or 4k). You also may want to build python with debugging. If that doesn't solve your problem, you will need to provide more information about how to reproduce your problem. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1429585&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
