This could be many things. A bug or race on the client side is possible,
but it could also be that the network session really _is_ being
disconnected. This could be something in the network stack itself
terminating the connection, or it could be a bug or other error on the
server.
Some things to consider/try:
- you can run with GIT_TRACE_PACKET=1 set in the environment, which
will dump the protocol messages that Git sees (this may not be
enlightening since the problem case seems to be a hangup, but
perhaps the moment it happens will be relevant)
- you didn't say which protocol you're using. If it's http, try
setting GIT_TRACE_CURL, too, and it will dump debugging data about
the http session
- if possible, try a different protocol (like ssh) and see if the
problem continues to show up
- look at server-side logs to see how the server perceives the
sessions. Does it report any errors that might cause it to hang up?
Does it see a client-side hangup (which might be indicative of
something flaky in the network)?
