I'm running 250+ pmies on my machine now, and running pmie_check
in a loop with a 10-sec delay between runs - so far, no luck in
reproducing the problem.  I'll leave it running overnight.

Reading through pmie_check.sh hasn't resulted in any additional
insight either.

So, guess that's our best bet for tracking this down further, at this
stage (sh -x /usr/share/pcp/bin/pmie_check.sh -V -V would be the next
step after that I suppose, but back up a dump truck for the amount of
data that will produce!).

cheers.
