[Pkg-nagios-devel] Bug#716949: nagios-nrpe-server: removes its PID on connection errors

[Bernd Zeimetz]

Package: nagios-nrpe-server
Version: 2.13-3
Severity: serious
Tags: patch

Hi,

after being scanned by nmap or just with a simple tcp health check, it
restarts itself but seems to fail to create the pid file again - so
stopping or restarting the nrpe daemon fails, which will break all upgrades.

A longer discussion and a patch can be found here:
https://bugs.launchpad.net/ubuntu/+source/nagios-nrpe/+bug/1126890

Interestingly I was not able to trigger the bug on all wheezy machines,
but didn't find the time to figure out why.

But this should not happen anyway:
nmap sT -p 5666 hostname

Jul 15 11:12:01 hstname nrpe[30261]: Error: Network server getpeername()
failure (107: Transport endpoint is not connected)
Jul 15 11:12:01 hostname nrpe[30261]: Cannot remove pidfile
'/var/run/nagios/nrpe.pid' - check your privileges.
Jul 15 11:12:01 hostname nrpe[30261]: Daemon shutdown


A fix in wheezy would be appreciated.

Thanks,

Bernd
