Well, it's not a shell variable, but /etc/profile says "ulimit -S -c 0" 
to "turn off" core dumping.   I suspect that you are re-enabling it in 
your own profile.   If you want to enable core dumping for a specific 
daemon, then either start it from your own shell directly or put an 
appropriate ulimit in the dameon's start-up script.

I generally don't do this -- if a daemon is likely to be core dumping, I 
attach the debugger to the running process and wait for it to crash.
