Something disconnected the client. Maybe you've a
firewall/load-balancer/etc in the middle that doesn't like long idling
connections? Although that wouldn't explain why it worked with v1.1.

You could also try it yourself:

telnet imap.server.com 143
a login user pass
b idle

and see if it gets disconnected. It should also send "* OK Still here"
every 2 minutes, so I'd guess nothing should disconnect it..
