    Hi,

    I'm having huge problems with "No buffer space available" errors. I've increased MAXUSERS to 512 in the kernel, recompiled, rebooted and the sysctl values below show that everything is up'ed to the max.
     
    some details which may help are:

        kern.maxfiles: 10796
        kern.maxfilesperproc: 9716
        kern.ipc.maxsockbuf: 262144
        kern.ipc.somaxconn: 65000
        kern.ipc.nmbclusters: 65000
        kern.ipc.maxsockets: 65000

    netstat -m reveals:

        70/400/260000 mbufs in use (current/peak/max):
                67 mbufs allocated to data
                3 mbufs allocated to packet headers
        64/208/65000 mbuf clusters in use (current/peak/max)
        516 Kbytes allocated to network (0% of mb_map in use)

    Any executable i try use which uses sockets has problems, for example rsync:

        socket: No buffer space available
        rsync: connection unexpectedly closed (0 bytes read so far)
        rsync error: error in rsync protocol data stream (code 12) at io.c(165)

    Can anyone help?

    Regards,

    James
