Major problem with "No buffer space available" errors

[James West]

The machine has 256Mb of RAM, 36Gb  scsi drive and is a 1.3Ghz AMD cpu.

I've switched MAXUSERS back to 0 now, right now before reboot my mbuf sysctl values read:

# sysctl -a | grep mbuf
kern.ipc.mbuf_wait: 32
kern.ipc.nmbufs: 260000

I'm stumped, stumped like a tree!

James.
