requests for mbufs denied

[Gabor MICSKO]

Hi!

I have a relative high traffic server, running Apache, MySQL and Drupal.
With FreeBSD 6.0 and 6.1-PRERELEASE i got some distressing "netstat -m"
outputs.

Can anybody explain for me what does this message mean exactly?

"16064849/9164254/9384500 requests for mbufs denied (mbufs/clusters/mbuf
+clusters)"

And what can i do with this?

Full "netstat -m" output:

$ netstat -m
445/695/1140 mbufs in use (current/cache/total)
407/255/662/65536 mbuf clusters in use (current/cache/total/max)

Sorry for my bad english.

Thank you!
