I just upgraded to 6.08 from 6.07 and now almost all my users are getting the login screen but it just gets stuck on "loading". Once in a while I can get through although it takes 20+ seconds for the mail screen to load.

I'm able to get into the admin console (after 20+ seconds) and I don't see anything in the logs. I've cleared cache on both Firefox and IE and both are just hanging. Rebooted server, restarted Zimbra 100 times,etc...

Any ideas here? Lots of people mad at me. Thanks.
