Hi
From your message below, you seem to be running out of mbuf clusters.
You need to modify NBMCLUSTERS in your kernel config file in
/usr/src/sys/i386/conf/ and set
options NBMCLUSTERS=dd
where dd is a number greater than the current max. Just how much will
depend on your particular circumstances.
Recompile the kernel and that should be all.
Hope this helps.
Thanks.
Richard
