this was more likely due to running out of memory rather than -M 
parameter. Parsing the config file consumes pkg and there are cases when 
the out of memory was not properly handled.

I committed a patch on master branch that should stop the startup 
process if parser runs out of memory.

Cheers,
Daniel
