(hope this goes to the right list.  this is regarding PR#454 which i
filed a few months ago.)

i upgraded to Apache 1.2b10 and removed one of the two processors on
the machine.  it crashed within 24 hours.

if there is anything i can do to help debug the situation, please let
me know.  this problem has been consistent since 1.2b8 -- 1.2b7 seemed
somewhat more stable but still had the problem.
