No, it's not a public server, sorry.  It's running apache 2.2.15, with mod_wsgi 3.3, on a 64-bit RHEL5 machine.

I can get various settings and debug logging changed to help investigate this, but I need to go though our "systems team" to do that so anything you ask me to try will take some coordination on my part to get it changed.  (i.e. a "quick 5 minute change" isn't)

btw, here's some output from hg push --debug if it's useful:

Perhaps that 0 length send at the end has something to do with the problem?
