>Description:
tcp4       0      0 192.168.0.26.9939      192.168.0.195.11211    TIME_WAIT
netstat -an | awk '{if($5 ~/11200/ && $6 ~/TIME_WAIT/) print $0}' | wc -l
   64203

sysctl net.inet.tcp.msl
net.inet.tcp.msl: 2500


msl will not recycle "TIME_WAIT" states when have lots of "TIME_WAIT",like 64203
so server local port will Exhaust&#65292; if i open a connection it will report:
telnet 192.168.0.195 11211
Trying 192.168.0.195...
telnet: connect to address 192.168.0.195: Can't assign requested address
telnet: Unable to connect to remote host


what can i do? only reboot server?
