Gerd -

Does this happen regularly on successive attempts?  Two things to look 
at when this happens:

1. Does the web interface say that external commands are disabled?

2. Don't delete the retention file right away.  The program{} entry at 
the beginning of the file should contain information needed to debug 
this problem.  Perhaps something is happening that is causing Nagios to 
write the incorrect values to the retention file, thus disabling 
external commands when it reads from the file after it restarts.

I just wrote a script that restarted Nagios 100 times using an external 
command, and submitted a passive check after each restart. Nagios came 
through okay, so the problem will take a bit of work to fix.
