bug#1125: 23.0.60; Occasional hangs in redisplay


From: Markus Triska
Subject: bug#1125: 23.0.60; Occasional hangs in redisplay
Date: Thu, 09 Oct 2008 01:31:48 +0200

In Ubuntu Intrepid, I have an "emacs --daemon" instance that I
occasionally connect to via "emacsclient -t". The daemon watches log
files etc. After a few days, the daemon consistently hangs, taking lots
of CPU time, and I cannot connect to it any more. When I attach gdb to
it, the backtrace always looks as follows. The hanged instance is still
running, and I can give more information about any values if needed.
