Can anyone else recreate the core dumps that Mladen is seeing with
the balancer in 2.1.7-beta? The httpd-test perl framework has a simple
test for it.
I can confirm Mladens core dumps. I used the latest revision from svn
and did the following:
./configure --prefix=/usr/src/apache/apache_trunk \
--with-mpm=worker \
--enable-so \
--enable-mods-shared=all \
--enable-proxy=shared \
--enable-proxy-balancer=shared \
--enable-proxy-http=shared \
--enable-proxy-ajp=shared
make
make install
I added the following lines to the default httpd.conf
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
<Proxy balancer://cluster>
BalancerMember ajp://localhost:8009
</Proxy>
ProxyPass /servlet-examples/ balancer://cluster//servlet-examples/

Putting
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
before
LoadModule proxy_module modules/mod_proxy.so
in httpd.conf results in
httpd: Syntax error on line 101 of
/usr/src/apache/apache_trunk/conf/httpd.conf: Cannot load
/usr/src/apache/apache_trunk/modules/mod_proxy_balancer.so into server:
/usr/src/apache/apache_trunk/modules/mod_proxy_balancer.so: undefined symbol:
proxy_module
So this does not "fix" it either.
My load order (in the perlframework/t/conf/httpd.conf) was...
mod_proxy
mod_proxy_ajp
mod_proxy_balancer
mod_proxy_connect
mod_proxy_http
mod_proxy_ftp
Does that affect anything if you reorganize?
