What does "netstat -n | grep 127.0.0.1 | wc -l" show ?

You should probably try

sysctl -w net.inet.ip.portrange.first=49152
sysctl -w net.inet.ip.portrange.last=65535

or even

sysctl -w net.inet.ip.portrange.first=1024
sysctl -w net.inet.ip.portrange.last=65535

And after you upgrade to 4.10 do not forget to set

sysctl -w net.inet.ip.portrange.randomized=0
