Strange, I can't remember having the same problem.

You could try setting /proc/sys/fs/suid_dumpable to 1. But this is a 
security issue on a production server, read the proc man page to see 
if it is acceptable.

Also, look into /etc/apache2 for coredumps, too. There is a short time 
period during restart where the core dump directory will be set to the 
compiled-in server root directory (I think this is a bug).
