these errors don't happen every time and i've yet to be able to

sort of memory corruption problem, but i'm at a loss as to how to
find it. i do have NSZombieEnabled set to YES and CFZombieLevel set
to 3.
can anyone one offer suggestions as to how to find this problem.
Turn on Guard Malloc, which will force your app to crash if
something writes into freed memory. Be ready to do something else
while it's running, though, because Guard Malloc makes your app run
super slow, especially if it uses a lot of RAM.

thanx nick,
my app is still in the early stages, and thus small enough that
turning on guard malloc isn't that bad. of course now that its turned
on, i no longer get the crashes! i guess i'll run in this mode for a
while.
thanx,
ken
