Agent stuck ESTAB socket with no LISTEN on port used by forwarder

[ashangit]

We observe issue restarting forwarder due to localhost:33000 socket being already used.
Looking at the server there is in fact an ESTABLISHED socket from a container with no LISTEN socket that blocks restart of forwarder.

> ss -np|grep 33000|grep ESTA

Netid  State      Recv-Q Send-Q Local Address:Port           Peer Address:Port    
tcp    ESTAB      956002 2604984 127.0.0.1:33000              127.0.0.1:33000               users:(("java",pid=46695,fd=28542))  

Could be linked to #17 but no real insight to prove this so far
