Description Andrej Manduch 2014-10-30 14:28:30 UTC 
+++ This bug was initially created as a clone of Bug #1158932 +++

Description of problem:

Irqbalance will exit on every single signal which receive except SIGHUP (which is ok).

When irqbalance receive SIGINT it will unlink pidfile and exit correctly (this is still ok). However if irqbalance receive another signal It will just crash (it will exit but without unlinking pidfile)

irqbalance crash even when receives `innocent` signals like SIGUSR1...

I'm not sure if this is bug or desired behaviour however I'll be happy if somebody will take look at that.
