Some more info on this one.  A call trace on the child processes looks
like this:

> /usr/proc/bin/pstack 4858
4858:   bin/httpd -f /u/www/conf/httpd.conf
 ef5b6fcc fcntl    (e, 7, fa69c)
 ef5b6fcc _libc_fcntl (e, 7, fa69c, ef5b8878, 0, 0) + 8
 ef74aba8 s_fcntl  (e, 7, fa69c, fa400, 40, effff81c) + 164

 00044b20 child_main (1a, 43740, 43400, 108, 0, 0) + 260
 00045270 make_child (129a58, 1a, 34cf646b, 0, 3e8, 0) + 168
 000456f4 perform_idle_server_maintenance (0, effffb84, 0, 129a58, be8b0,
b9cb0) + 31c
 00045c58 standalone_main (3, effffcac, e9400, 0, 0, 0) + 4cc
 00046304 main     (3, effffcac, effffcbc, 1250d0, 1, 0) + 458
 00020598 _start   (0, 0, 0, 0, 0, 0) + 5c

And a trace on the parent process shows:

> /usr/proc/bin/pstack 23685
23685:  bin/httpd -f /u/www/conf/httpd.conf
 ef5b782c poll     (efffdaa0, 0, 3e8)

 00043630 wait_or_timeout (effffb84, effffb84, 0, 129a58, be8b0, b9cb0) + cc
 00045b04 standalone_main (3, effffcac, e9400, 0, 0, 0) + 378
 00046304 main     (3, effffcac, effffcbc, 1250d0, 1, 0) + 458
 00020598 _start   (0, 0, 0, 0, 0, 0) + 5c

Mutex problems?
