[TYPO3-mvc] CommandController in TYPO3 6.x never runs

[Domi]

Hello,

Sorry for my crosspost from the english list, but hopefully here Ill 
find an answer.

I have a problem with Scheduler and a CommandController. The task is 
always marked as "Late, will run with next execution". But it never happens.

Frequency is set to
0 8 * * *
for running every day at 8 oclock.

Last execution is only my manual tested execution it never ran again.

Setup check does not give any error. What could be the problem?

Thanks,

Best Regards
Dominic
