[Bug: 21.4.14] XEmacs hangs when doing networking

================================================================ Dear Bug Team! XEmacs regularly hangs when doing networking. I use Gnus and read news from several news servers (and IMAP accounts). What often happens is that XEmacs just hangs and stops responding if anything goes wrong with a network connection. There seems to be no timeout, e.g. once it's hung, it will stay that way (I've waited several hours). Nothing is redrawn, there is just a blank XEmacs window. The common recurring theme is the two messages that appear on the console that XEmacs was started from: X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 25 (X_SendEvent) Resource id in failed request: 0xe009ba Serial number of failed request: 593927 Current serial number in output stream: 594059 Xlib: unexpected async reply (sequence 0x9108b)! xemacs-21.4.14: X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 18 (X_ChangeProperty) Resource id in failed request: 0xe009ba Serial number of failed request: 593926 Current serial number in output stream: 594059 The X requests are always the same, only the parameters change. After being killed XEmacs sometimes produces a Lisp backtrace, which usualy points (unsurprisingly) to network code, as in: # (unwind-protect ...) # (unwind-protect ...) accept-process-output(#<network connection "nntpd<2>" ("nntp" . "news-server.san.rr.com") state:exit> 0 100) # bind (process) nnheader-accept-process-output(#<network connection "nntpd<2>" ("nntp" . "news-server.san.rr.com") state:exit>) # (unwind-protect ...) # bind (process) nntp-accept-process-output(#<network connection "nntpd<2>" ("nntp" . "news-server.san.rr.com") state:exit>) # (unwind-protect ...) # bind (process wait-for buffer decode discard process timer pbuffer buffer) nntp-open-connection(#<buffer " *nntpd*">) [...] As this is happening to me several times a day now, it is extremely annoying. I seem to remember being able to keep XEmacs running for weeks: has something changed, or have I started connecting to flaky services? And, most importantly: what can be done about it? thanks, --Jan ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Linux tnuctip.rychter.com 2.4.22 #3 Thu Sep 18 20:48:53 PDT 2003 i686 i686 i386 GNU/Linux ./configure '--with-mule' '--error-checking=none' '--with-menubars=lucid' '--with-scrollbars=lucid' '--with-dialogs=athena' '--with-widgets=athena' '--with-athena=3d' '--with-sound=no' '--pdump' XEmacs 21.4.14 "Reasonable Discussion" configured for `i686-pc-linux'.
