If there's a race why hasn't it been fixed in the main tree?
A swap issue makes sense. If I've been down long enough I get
swamped with email when I come back up. A bug in the latest
procmail yields 130M processes that fill up swap and make
the system be swap bound. The solution is the following
patch to procmail.

Since going from a SMP to nonSMP kernel the Hard Locks don't seem to be happening.

The enclosed patch might help. Disabling swapping (sysctl vm.swap_enabled=0) can also help. - Tor Egge
