Corinna,

I tried "rebasing" but with no luck.

The problem appears when I am running 60 scripts in parallel on a 32
core machine. Plus, each script runs subscripts with several pipes.
So, I think this is a "too many processes" type of issue.

Usually, windows handle my "over-coring" well and my machine just
works through what it needs to do. But when I try this from Cygwin, it
seems to cause issues.

Any thoughts or suggest for how I could get around this?

Moon
