I am running a Rails application with Apache 2.4.10 and mod_passenger
. The site uses https exclusively. I am seeing these messages in my error log:
[Wed May 31 19:05:37.528070 2017] [reqtimeout:info] [pid 11111] [client 10.100.23.2:57286] AH01382: Request header read timeout

These messages appear in the error log about two to three seconds after the end of my page load. However, the complete page load takes only a few seconds. I am using mod_reqtimeout
with this setting:
RequestReadTimeout header=20-40,minrate=500
Since the page load only takes a few seconds I do not understand why the Request header read timeout
messages are being logged to the error log.
Why are these messages appearing and what can I do to remedy this?
