[torqueusers] many server-client connections in TIME_WAIT

[Arnau Bria]

Hi all,

our server has many connections from clients in TIME_WAIT status:
# netstat -puta|grep pbs|wc -l
1071

[...]

If I restart pbs_server, all of them die, but after few second I have
1000 conncetions again.

What could be blocking the socket to be closed?
