I just experienced the same thing: after about 30 minutes, offlineimap
hangs. The last lines (debug info was on) were:

DEBUG[imap]: imapsplit() returning: ['FLAGS', '(\\Answered \\Seen)',
'UID', '2']
DEBUG[imap]: options2hash called with input: ['FLAGS', '(\\Answered
\\Seen)', 'UID', '2']
DEBUG[imap]: options2hash returning: {'FLAGS': '(\\Answered \\Seen)',
'UID': '2'}
Next sync in 1:00
2: [active]      *Control: .
1: [  0:27]           Sam: .   

(last three lines are from Curses.Blinkenlights, problem occurred also
with Tk interface)

Note that the counter was at 0:27 second: I think there was no
activity at this time. I was running with two threads.

I am running FreeBSD 4.7-STABLE and the server is courier-imapd on
Debian (Sparc64), with holdconnection=yes.
