Maybe there's something going on in another thread? Can you try "thread apply all bt" in gdb? Also is avahi-debuginfo installed?

It is not needed to change runlevels to trigger the bug, rcavahi-daemon restart is enough. It only happens when avahi-daemon is started as daemon ("avahi-daemon -D"). Starting avahi-daemon not in daemon mode won't trigger the bug. Starting avahi-daemon with --debug doesn't give any useful information about what it is doing.

I have stepped execution of the program and have found the difference: It seems to lie in simple-watch.c, function avahi_simple_poll_dispatch. If the bug is triggered, the conditional in line 550 "if ((next_timeout = find_next_timeout(s))) {" always fails, and the program runs the loop commented as "/* Look for some kind of I/O event */" in lines 568-580.

Sorry, forget this. A second attemp showed no such difference. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
