freebsd stable - Jun 2005 - panic: kmem_malloc(4096): kmem_map too small: 62877696 total allocated

Got the following panic on a 5.4 box(i386):

panic: kmem_malloc(4096): kmem_map too small: 62877696 total allocated

Uname: 5.4-RELEASE FreeBSD 5.4-RELEASE #4: Sun May  8 01:57:26 CEST 2005

Had two ntfs partitions mounted and was doing a find . -name *.pst on one of
them.

Following info collected, but kernel dump aviable if more information is
needed.

How much RAM in your system, and what is your kernel config?  This can
be caused by two things:

* A memory leak in FreeBSD

* Incorrect tuning of your kernel memory parameters and causing the
kernel to run out of memory.

RAM: 
	real memory  = 201326592 (192 MB)
	avail memory = 187273216 (178 MB)

Havent done any kernel tuning and running with a mostly generic kernel
(changes to GENERIC below):

	options         IPFIREWALL
	options         IPFIREWALL_VERBOSE
	options         IPFIREWALL_VERBOSE_LIMIT=400
	options         IPDIVERT
	device ath
	device ath_hal
	makeoptions     DEBUG=-g                # Build kernel with gdb(1)
debug symbols
	options         KDB
	options         DDB                     # Enable the kernel debugger
	options         BREAK_TO_DEBUGGER
	options         DEBUG_LOCKS
