That's a bit big to be useful, and far bigger than I'm willing to
download given that I'm on the end of a wet piece of string, not a
big fat intarwebby pipe. I'm assuming it is the event trace
that is causing it to blow out? If so, just the 30-60s either side of
the hang first showing up is probaby necessary, and that should cut
the size down greatly....

Cheers,

Dave.
