Yes, I know I didn't copy the whole 100 lines.

I heard about a ULIMIT setting that caps memory or cpu usage, could
dissabling it help with this problem?  And if so where is this setting?

I will try tweaking verynice and let you know what it does, but I must
say I don't have a lot of hope for it.  Still it is worth a try.

Thanks,
