Socket limit exceeded here.
You can increase this limit using sysctls:
net.graph.recvspace=2048000
net.graph.maxdgram=2048000
But, it also can't exceed kern.ipc.maxsockbuf
Quick, example:
mk_ngeth.sh:
#!/bin/sh
for i in `jot 1000`
do
ngctl mkpeer . eiface test ether
done
# sh mk_ngeth.sh
# ifconfig |grep ngeth|wc -l
1000
# sysctl net.graph.recvspace
net.graph.recvspace: 20480
# sysctl net.graph.maxdgram
net.graph.maxdgram: 20480
# sysctl kern.ipc.maxsockbuf
kern.ipc.maxsockbuf: 2097152
# ngctl ls
ngctl: send msg: No buffer space available
# sysctl kern.ipc.maxsockbuf=32000000
kern.ipc.maxsockbuf: 2097152 -> 32000000
# sysctl net.graph.recvspace=24000000
net.graph.recvspace: 30000 -> 24000000
# ngctl ls | wc -l
1002
