[Bug 897161] [NEW] Apache2 incorrectly sends HTTP_REQUEST_TIME_OUT to many requests

[Francis Rath]

Public bug reported:

As it is fairly difficult to debug 408-errors on a live server (for me
at least) I am not sure about the cause of this, but it happens in about
3% of all requests since upgrading from 2.2.14-5ubuntu8 to
2.2.14-5ubuntu8.7 (about 10.000 times yesterday).

I have tried disabling the reqtimeout-module, but to no avail. Have also
tried with KeepAlive On/Off (I have it enabled for my site that gets
frequent POSTs from active users).

Downgrading to 2.2.14-5ubuntu8 fixed the problem, and after looking
through the changelogs I am suspecting a change in server/protocol.c to
be the source of the problem:
http://launchpadlibrarian.net/84878468/apache2_2.2.14-5ubuntu8.6_2.2.14-5ubuntu8.7.diff.gz

Please let me know if I can give any more helpful information. This has
been temporairly fixed by forbidding the problematic version and
downgrading.
