I have about 25 users on Zimbra CE version 1.4.9. I just upgraded to 1.4.9 a couple of days ago. Today the users started complaining that their pop3 clients were not getting any email. I checked the server and did a 'netstat -a' and found over 700 pop3 connections that were not closing. I think they were in the TIME_WAIT state. Anybody have any idea what would cause that, and how to fix it?
