Most of the relevant sockets (that is, between the two host mentioned) are in the ESTABLISHED state (200-400 of those). Only 20-40 are in TIME_WAIT state (these tend to be from a more ephemeric POP3 service). Most of the EADDRINUSE happen for the IMAP4 service. -- Jan Srzednicki :: http://wrzask.pl/ "Remember, remember, the fifth of November" -- V for Vendetta
