 The problem persisted regardless of whether there was a 
 /etc/nsswitch.conf file so I spent some time and think I have it 
 figured out. I have mail/squirrelmail installed which depends on 
 lang/php4 which in turn depends on security/php4-mhash. mhash was 
 trying to use the libpthread.so. At one point this machine ran CURRENT 
 but I reverted back to 5.2.1. I had an old libpthread.so which mhash 
 linked against. The crash was apparently confusion between the 
 different threading libraries. I had to remove the libpthread and setup 
 a libmap.conf to use libthr.so.
 
 Now httpd survives a HUP signal like it was meant to.
 
 Thanks,
 Greg
