Description

I get this in the vkernel, usually when I exhaust the mbuf objcache.

The bug is the "mfree: m->m_nextpkt != NULL" message, not the mbuf
exhaustion (while testing async write BIOs w/NFS I didn't slap any
limits on how many it tried to run in parallel) <GRIN>.

Hi Matt,

How do you exhaust mbufs?

Cheers,
