HGWeb/Jenkins problems

Hi, I sometime end up with the following error too (made 2 repos pull that
work from the same host and one that failed, retry work for all 3 of them):

Seem like I got some network problems, is there any way to
troubleshoot this? I feel like the server are well setup and work most
of the time and sometime I end up with those nasty error. Network
fluke or data corruption or is it simply packet lost? Look like some
data are not making it from the hgweb server to the Jenkins server for
some obscure reason.

If someone have a way to troubleshoot this intermittent problems on a
network I would be glad.

Nothing into the error log. I'm a bit confuse about what can cause this, I double checked the network config of all machine imply into this and nothing seem to be wrong (ipV4, ipV6, hostname, domain) everything seem to be fine and ping work flawlessly under 0.75 ms. Anybody have a clue or a way to check what happen into those case? what is happening that close the stream (host unreachable, timeout, ...)?
