[Nagiosplug-help] Error: Could not complete SSL handshake

[Alastair Battrick]

Hi

I'm having an intermittent problem with NRPE. I have NRPE 2 and Nagios 
plugins 1.4 alpha1 installed on a RH9 box. The server is very heavily 
trafficed by search engines, and the load is near constantly at 15+.

I have this same setup on about 10 other machines, and all of them run 
fine, without this problem

NRPE is running with --daemon and is queried by Nagios 1.1 running on a 
different server.

The problem is that syslog on this heavy load machine is giving the 
following errors:

---------------------

---------------------

Nagios is checking this machine every 3 or 4 minutes, so this is not 
happening on every check, and also, if I "su - nagios" and run a 
command, I do not get this error. When the errors are logged above, 
Nagios checks fail, as NRPE timed out after 30 seconds

Anybody any suggestions?
