I'm a beginner but I did install fpm to see how it works.
Did you set the fpm acces logs?
; The access log file
; Default: not set
access.log = "/usr/local/etc/php/8.0/log/www.access.log"
And the status page?
; The URI to view the FPM status page. If this value is not set, no URI
wil
Yeah the 408 is not easy to troubleshoot it might be anything from
malformed HTTP header and slow client (i.e. legit DoS attack where a
malicious client sends the headers and then delais sending the request body
in order to keep the connection open and exhaust server side resources) to
a legit netw
Also worth noting that Nginx OS does not experience the issues (otherwise
same setup)...

Yeah, all those parameters are configured and everything works fine when I
switch to the MPM worker module. The 408 errors are returned by Jetty and
ProxyPass is configured to not reuse connections (which seems to suggest
not a KeepAlive issue), Jetty is erroring because it receives no request
data
I will still say this is a timeout issue. Set the ALB timeout to 3600 which
is the max possible in case you do not know where to start from. I guess
you already have ALB logs enabled.
In apache check the KeepAliveTimeout, RequestReadTimeout and ProxyTimeout
and make sure they make sense for your u
Thanks for the response. Timeouts are configured appropriately...
To clarify; everything works fine through a TCP Network Load Balancer
pointing at the same infrastructure. There is something about having a HTTP
based Application Load Balancer in front of an MPM event configuration
that's causing
In a proxy chains like this getting the timeouts in sync is the most
important thing. Make sure that you have done that.

Hi All,
I've been experimenting with the MPM event module with Apache instances
sitting behind an AWS Application Load Balancer (ALB) and it really doesn't
seem to be working well. Response times shoot up (compared to MPM event
worker) and we see a fair few 502 errors returned (by the AWS ALB.
