#5 stop receiving messages

[Anonymous]

Every time I'm in the middle of a conversation with
somebody, at some point I stop receiving their
messages. So to me, it seems like they aren't
responding to me anymore. To them, everything seems
to work...they are getting all of my messages and
replying to them fine. Sometimes this happens as soon
as I start the conversation, and other times it has
happened 30 minutes into the conversation. It does
not seem to have anything to do with me being idle.
Sometimes I'll get a message, reply a few seconds
later, and miss the next message that they send a few
seconds later.
On my side, I stay online the whole time. Remotely,
my friend mentioned that I appeared to be going
offline for a few seconds and coming back, but I'm not
sure if this happens all the time.

I am running tnt-2.3.2 on emacs-20.5.1.
If it's relevant, my idle timers are buggy (according
to the test).
