I'm running a heavily loaded NFS server, and I am now seeing (occasionally) things like: yp_next: clnt_call: RPC: Unable to send; errno = No buffer space available yp_next: clnt_call: RPC: Unable to send; errno = No buffer space available yp_next: clnt_call: RPC: Unable to send; errno = No buffer space available My NIS client software is complaining "No buffer space" available. Here is output from netstat -m: 178/38224/131072 mbufs in use (current/peak/max): 174 mbufs allocated to data 4 mbufs allocated to packet headers 131/32768/32768 mbuf clusters in use (current/peak/max) 75092 Kbytes allocated to network (33% of mb_map in use) 581 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines Notice the "memory denied" numbers.. /etc/sysctl.conf: vfs.nfs.gatherdelay=0 vfs.nfs.async=1 vfs.vmiodirenable=1 kern.ipc.maxsockbuf=2097152 kern.ipc.somaxconn=8192 kern.ipc.maxsockets=16424 kern.maxfiles=65536 kern.maxfilesperproc=32768 net.inet.tcp.rfc1323=1 net.inet.tcp.delayed_ack=0 net.inet.tcp.sendspace=65535 net.inet.tcp.recvspace=65535 net.inet.udp.recvspace=65535 net.inet.udp.maxdgram=57344 net.local.stream.recvspace=65535 net.local.stream.sendspace=65535 net.inet.ip.forwarding=1 Anything else I'm missing?
