We too are seeing connection drops several times a day. Connecting Python to
imap. It's usualy a broken pipe or Connection reset by peer. Sometimes "bad
write retry" as well.  I thought this was an issue with our isp, but now I'm not
so sure. Do you have any details about what the "cases" might be? I saw mention
from google themselves about "folders being too big" and that's certainly a
possibility, I haven't been able to explore it yet.

Some code that might be handy for testing this:
It was failing reliably yesterday, but I haven't seen it fail today. 

# execute via "python scriptname 'username' 'password'"
import imaplib
import sys
I = imaplib.IMAP4_SSL('imap.gmail.com', 993)
rc, resp = I.login(sys.argv[1], sys.argv[2])
I.select('Inbox')
rc, msgs = I.search(None, 'ALL')
for msg in msgs[0].split():
    print 'Getting msg body'
    rc, data = I.fetch(msg, '(BODY.PEEK[TEXT])')
    print '...Length is %s, response is %s'%(len(data), rc)
I.logout()
