Fixed In Version:	irqbalance-1.0.7-2.el6	Doc Type:	Bug Fix
Doc Text:	Previously, the irqbalance utility did not set signal handlers for particular signals. Consequently, when irqbalance received a signal other than SIGINT or SIGHUP, it terminated without a cleanup. This update provides signal handlers for SIGUSR1, SIGUSR2, and SIGTERM. As a result, irqbalance now stops gracefully after finishing the current balancing iteration.	Story Points:	---

Description Andrej Manduch 2014-10-30 14:24:35 UTC

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.
