Ed,

I have seen the same thing happening occasionally on the two machine 
running IC here.

   1.    RH 7.1, Apache 1.3.23, PgSQL 7.1.2, 640 Mb Ram, IC 4.8.3, High 
Traffic Mode, mod_interchange, yadda yadda..
   2.    RH 7.2, Apache 1.3.23, PgSQL 7.1.2, 256 Mb Ram, IC 4.8.3, Low 
Traffic Mode, mod_interchange, yadda yadda.

Looking through the archived logs back to March, I find the following:
Machine 1:
   [Tue Apr  9 11:59:24 2002] [notice] child pid 20045 exit signal 
Segmentation fault (11)
Machine 2:
   [Mon Mar 18 11:57:56 2002] [notice] child pid 16242 exit signal 
Segmentation fault (11)
   [Mon Mar 18 11:58:18 2002] [notice] child pid 16351 exit signal 
Segmentation fault (11)
   [Tue Mar 26 10:51:38 2002] [notice] child pid 911 exit signal 
Segmentation fault (11)
   [Wed Apr 24 11:10:56 2002] [notice] child pid 24115 exit signal 
Segmentation fault (11)
   [Wed Apr 24 11:12:44 2002] [notice] child pid 24001 exit signal 
Segmentation fault (11)

All IC development is done on Machine 2.
I had put it down to misconfigurations, or fatal coding errors, which do 
occur on the dev server but
theoretically dont on the live server...
hmmm...rethink occurs...
