Description

Core uses 100% cpu at certain times.

History

#1 Updated by mattwb65 over 10 years ago

It appears to be caused by adding network to Quassel. It crashes while still using 100% cpu. Perhaps dead socket or something?

#2 Updated by Anonymous over 10 years ago

Adding networks is done by many people without issues. If it crashes, you might end up with a backtrace in the configdir, if not, do the following:

Make sure you have symbols for quasselcore (distro-specific), start quasselcore with gdb (`gdb quasselcore` and 'run' at the prompt) and send a SIGTERM (^C) when it hangs. It'd be nice if you could paste the output of bt (look at http://www.yolinux.com/TUTORIALS/GDB-Commands.html for a cheatsheet which also covers logging to a file).

If you feel like spending some more time debugging this, try doing it a few times to find a common denominator and try stepping through the code (see the cheatsheet for details).
