5.3: tmpmfs="YES": panic: kmem_malloc(4096): kmem_map too small: 63737856 total allocated

[ls+lists.freebsd.org.mailman.listinfo.freebsd-stable93930659 at gambit.com.ru]

	I'm using

> uname -v
FreeBSD 5.3-STABLE #0: Sun Oct 31 04:03:03 UTC 2004

	Want to use /tmp in memory:

> grep tmp /etc/rc.conf
tmpmfs="YES"
tmpsize="384m"

	Using swap space, not just RAM:

> diff -u /usr/src/etc/rc.d/initdiskless /etc/rc.d/initdiskless

 }

 # Create the memory filesystem if it has not already been created

	But I'm still getting panic sometimes
	when trying to untar data to /tmp:

> dmesg | grep -A 3 panic

Uptime: 1d23h53m0s
Cannot dump. No dump device defined.
Shutting down ACPI

	This host has 192 MB of RAM:

> dmesg | grep memory
real memory  = 199753728 (190 MB)
avail memory = 189919232 (181 MB)

	And 512 MB of swap:

> swapinfo -k
Device          1K-blocks     Used    Avail Capacity
/dev/ad0s1b        524288    17412   506876     3%

	Is it a feature or a bug^Wproblem?
