AH... I see, instead of `maxMBpS=default -N all` try a specific number. And then revert to "default" with a second command. Seems there are some bugs or peculiarities in this code. # mmchconfig maxMBpS=99999 -N all # mmchconfig maxMBpS=default -N all I tried some other stuff. If you're curious play around and do mmlsconfig after each mmchconfig and see how the settings "evolve"!! -------------- next part -------------- An HTML attachment was scrubbed...
