Hi Christopher,

I was out last week, but we were able to gather a few more pieces of data.

1) We ran some tcpdumps, and nothing odd popped up at all. Given our traffic levels, we were actually surprised how few RST, etc. we had. Any TCP issues that did occur did *not* coincide with the SD-- log lines. 2) We've confirmed this also happens with similar rates on publicly served traffic, as well (which mostly uses varnish as the backend). The symptom is a slightly truncated response body.

That left us with the upgrade to 3.0.5 as the culprit, so we're going to need to rollback to 3.0.4 for now. If we have the time, we'll run some more tests on a limited subset of servers to see if we can find out anything more.


Thanks Luke for the info. For me, there are just few commits that may be related (with no explanation):

* e2a93b6492 ("BUG/MEDIUM: stconn: Report error on SC on send if a previous SE error was set")

* 0be5e36d8c ("BUG/MAJOR: mux-h1: Wake SC to perform 0-copy forwarding in CLOSING state")

* aa43ed1719 ("BUG/MEDIUM: http-ana: Report error on write error waiting for the response")

The first one is the best candidate. If you perform some tests, you can try to revert it.
