Main question I see following line in netstat. Does it means this socket doesn't belong to any process?
#>netstat -tpn|grep TIME_WAIT| head -1 tcp 0 0 ::ffff:127.0.0.1:5555 ::ffff:127.0.0.1:45845 TIME_WAIT -
In an multithread program can thread responsible for dealing with socket be already gone? (It's NOT in 'sleep' or 'uninterpretable sleep')?
