It means you've run out of room in the kernel VM map that manages
space used by mbuf clusters.  You can increase the size of this map
with the NMBCLUSTERS kernel option.  For example, on most ports, the
default size of this map is 256.  With the GATEWAY option, it is 512.
I typically increase it to 1024 on servers.
