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?
How can I fix this?
