Nagios hosts showing as down

[Matthew.Quinney at hollandandholland.com]

Dear All,

I have a strange problem with Nagios V1.1 using the plugins from v1.3.1.

I have a remote router which ordinarily is checked by 'check_http' every x 
minutes. In some cases the check fails (ADSL) so Nagios will then run the 
host check command 'check_tcp'. However in some cases this fails and just 
leaves the error message 'check_tcp: unknown argument (null). The majority 
of the time though this check runs just fine.

My questions is therefore, what am I doing wrong ? I have been running 
Nagios for some time (great stuff Ethan) and this has only cropped up in 
the last few months. If anybody has seen this, or can help I would 
appreciate it greatly.

Many thanks

Matthew
