>Description:
	Every few hours we are getting:

	     panic: cluster_rbuild: too much memory
	     syncing disks... panic: locking against myself

	     dumping to dev 401, offset 786432
	     dump 128 [...] 3 2 1

	We have crash dumps available.  This machine is a lightly loaded (0.14)
	outgoing newsfeed machine running customized software that allows
	it to mostly run out of ram.  Disk activity is under 10 transactions
	per second, on average.  A 8 meg md0 /tmp is being used.

	Process count is around 34.  Buffer cache is set to 32 megs.  Free
	mem is usually around 32 megs.  Interrupts per second is usually well
	under 500.

>How-To-Repeat:
	Unknown.  It just seems to happen on this machine.
>Fix:
	Unknown.
