Major problem with "No buffer space available" errors

Another thing you could try is compile for 0 users, this sets it to an
automatic value, depending on the machine specs, I had this prob, on a
server, and that fixed it.

Hope this helps

Are you running ipfw on the box? When I configured a
queue without a pipe to put it on, I got the same
message and couldn't ping hosts on that interface
until I removed the queue.
