Description sonnet 2001-09-04 13:20:01 UTC 
Basically, It is same problem as kern/20927.
But It makes actual trouble. If it happened, networking doesn't work properly(ex: can't login via network, etc).

In previous PR(kern/20927) itojun mentioned "out of mbuf" problem. 
But in my experience, machine's netstat -m report enough mbuf remained.

It seems like after enough progress of mbuf fragmentation, system couldn't get contiguous mbuf.
I got this problem twice, and that machine's uptime is 30day, 41day.

How-To-Repeat: Unfortunately, have no idea.

It is heavy loaded network server machine uses about 2500 connection via loopback interface.

I reopened 20927, so this one is now a duplicate.
