More digging into #2:

INTERNAL: Allocating one item from buf free cache(0x83fea7e0)
uma_zalloc_arg: Bucketzone returned NULL
INTERNAL: Allocating one item from buf free cache(0x83fea7e0)
uma_zalloc_arg: Bucketzone returned NULL

Something is getting wedged allocating a buf, failing, and sticking in
