Found the solution. Turns out there is a new module that needs to be
included, as follows:

LoadModule lbmethod_byrequests_module
/QSYS.LIB/QHTTPSVR.LIB/QZSRCORE.SRVPGM

Heyo,

I am trying to setup a proxy balancer and am getting an error of
"Cannot find byrequests lb method" with the below httpd.conf. I am on
v7.2 and have the latest PTFs installed (level 9 for SF99713) as of
last night. If I comment out the BalancerMember lines the error goes
away, but I need those lines :-) It tells me to add a directive, but
the directive syntax isn't correct, and I already have module

proxy_balancer_module specified.

Anybody see something wrong with what I am doing?

p.s. I included steps to recreate issue at bottom of email.
