Then this shows that Digital UNIX is especially vulnerable to the Perl
signal crash that is part of every Perl. Nothing you can do except
comment out the Sig_inc and Sig_dec, or put the Safe_signals stuff back
in. I would make the following settings to compensate:

PIDcheck   60
MaxServers 10
HouseKeeping 2

Pages that took more than 60 seconds to return (long uploads, imports,
and inefficient pages) would die a flaming death....

And I would make sure I had plenty of memory. 8-)
