Nagios3 crashes with SIGSEGV

  • 772

I installed nagios3 on ubuntu server 10.04.1. It was working fine.

Today, I found it stopped and when I tried to start it using sudo /etc/init.d/nagios3 start, it did not start. I found this in the log file:

Nagios 3.2.0 starting... (PID=11729)
Local time is Wed Dec 22 14:15:31 2010
Caught SIGSEGV, shutting down...

I tried to remove and re-install it without success. After googling, it seems that no one has a solution for this. I don't want to install it from source unless it is really the last hope.

10.04 server nagios3

  1. From the crash stacktrace I managed to work out that this is related to the Nagios update checking code. As a workaround, you can disable the update check, and Nagios should then work as normal (at least it does for me!). i.e. in /etc/nagios3/nagios.cfg set

    check_for_updates=0

    I've added the stacktrace and workaround to this bug report.

    I've seen a couple of cases of people with this problem.

    No-one seems to have reported a bug though - I would suggest you do this by pressing Alt+F2 and entering ubuntu-bug nagios3. This will greatly increase the chance that the Ubuntu nagios maintainers will be able to help you.
