A whole bunch of these so-called "linux problems" are because the people
run multiple servers with the same ScoreBoardFile.  At least that's what
I've been discovering.  It would be nice to have some way to detect when
two servers are trying to share the same file. 

I've been running my linux box with -DHAVE_SHMGET for weeks now without a

This problem is still occuring. It has only occured on two machines
ever, that I personally know of, and I can only observe it on the current
machine. The only thing that differentiates BOTH machines from all others
is the heavy use of DBM... and this problem seems to be there regardless
of kernel/apache version, but only occurs when a third copy of apache is
running. I think, although I can't be positive, that there is a trend in
that the server which dies off is the one with the largest amount of DB
access... perhaps a lib problem? or a kernel problem? Sorry to mail the
list if this isn't a kernel issue.

Even 2.0.29/ISS patch 4 suffers from this, haven't tried 2.1.x yet,
