Ok, here's a netstat -m from our cron script that restarts the tunnel
ping: sendto: No buffer space available
$netstat -m
392/704 mbufs in use:
309 mbufs allocated to data
83 mbufs allocated to packet headers
215/400/10000 mbuf clusters in use (current/peak/max)
888 Kbytes allocated to network (53% in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
This is a one-way tunnel flowing from a 3.5-STABLE machine to a
4.4-RELEASE box.
