xennet0: rx no buf after upgrading to NetBSD 7
I've upgraded a web-server from NetBSD 5/i386 to 7/amd64 and now I'm
frequently getting "xennet0: rx no buf". I don't think the server is any
busier than it was before, but I guess there could be sporadic DoS
attacks on it.
Of course, when I look now, it's all idle:
# netstat -m
5 mbufs in use:
1 mbufs allocated to data
3 mbufs allocated to packet headers
1 mbufs allocated to socket names and addresses
93318 calls to protocol drain routines
kern.mbuf.nmbclusters = 98304
I looked at this thread:
https://mail-index.netbsd.org/port-xen/2015/03/28/msg008611.html
While it may explain what is behind the message, it's short on ways to
mitigate it.
