Andreas,

It is good to hear some one say it's not something I have done in the 
configuration files that is causing the problem.

In 'ps -ef' I see no checks hanging.  Any where else to look ?

I use only the standard Nagios plugins.

As of this morning, Nagios is using 37% memory, so it is still going up.

Another thing which I believe I should mention here, I am also running NSCA on 
this machine, under the same user name.

Just for a bit more information, Nagios is now using 37% (from 'top').
