Some of my users are getting timeouts periodically in Thunderbird and
other mail clients when trying to access their mail folders. I enabled
DEBUG on IMAP (James R3B5). I'm seeing sessions lasting several minutes
with an ongoing "tag" count. I have a pretty good grasp of the IMAP
API and have written some standalone apps that interface with IMAP. But
I don't really understand what Tbird is doing. Is this 'tag' just
some ndx that Tbird keeps incrementing, and does Tbird just keep a
session open forever? I've got to wait until the hang occurs again on
Tbird for some client and then determine if the logs differ. But until
that time, I'd like a better grasp of what I'm seeing in the log below.
Can someone explain what is flowing back and forth below? Also, is DEBUG
the most granular I can go in JAMES log4j? I'd love to see when each
command completes and not just when it starts.
