requests for mbufs denied

[Igor A. Valcov]

I'm having the same problem on my home PC (Intel PRO/1000 adapter, em)

Here's the output from netstat -m

354/726/1080 mbufs in use (current/cache/total)
310/530/840/32768 mbuf clusters in use (current/cache/total/max)
708K/1241K/1950K bytes allocated to network (current/cache/total)
43900815/32119482/32108081 requests for mbufs denied
(mbufs/clusters/mbuf+clusters)
0/5/6656 sfbufs in use (current/peak/max)
0 requests for sfbufs denied
0 requests for sfbufs delayed
56 requests for I/O initiated by sendfile
2928 calls to protocol drain routines

The traffic coming through that computer is pretty low, around 40kB/s
in both directions at the average, 80kB/s max, so the fact that some
(let alone 43 million) of mbuf requests are being denied is puzzling
to say the least.
