You have something that eats (malloced) memory from the kmem_map.
vmstat -m tells how much eaten and by what, but when it already has
paniced it's a little bit too late :-)  Try to "call dump_kmemstats"
from ddb to see where the memory has disappeared. Note that KMEMSTATS
must be configured in your kernel.

If the kmem usage is legitime, you can increase vm.kmempages to a
higher level or compile the kernel with NKMEMPAGES set to a 
higher value.
