[Nagiosplug-help] nrpe spams my logs

[Jeroen Demeyer]

Hello list,

We installed nagios+nrpe on a cluster to monitor the health of our
nodes.  Nagios runs on a server, and the diskless nodes run nrpe.
This works fine, however, sometimes nrpe starts spamming the syslog:

Nov 13 13:46:51 node6 nrpe[10671]: Network server accept failure (22: Invalid argument)
Nov 13 13:46:51 node6 nrpe[10673]: Network server accept failure (22: Invalid argument)

Nov 13 13:46:51 node6 nrpe[10699]: Network server accept failure (22: Invalid argument)
(this goes on for a long time, >100 times per second)

I suppose this is a bug in nrpe?  Also, I shut down nagios on the server
but nrpe keeps giving these error messages, even hours after nagios was
stopped.  Any ideas how to fix this problem?

This is on a recent Gentoo system with nagios-1.2 and nagios-nrpe-2.0-r1,
2.4.26 openMosix kernel.
