ich überwache einige kleinere Boxen. Dabei habe ich hin und wieder folgenden 

OMD[site]:~$ cmk -vv --debug -d HOST

Wenn ich das "Programm" von Hand ausführe, habe ich nie einen Fehler.. 200 mal 
hinter einander und keine Fehler.
Sobald CheckMk im Spiel ist ca. 10 mal ok und 1 mal Fehler...

Wo kann ich hier noch genauer nachschauen um dem Fehler auf die Schliche zu 

Check_MK 1.6.0p5 CRE
