Paolo Lutterotti commented on MODCLUSTER-501:
---------------------------------------------

Hi Michal,
thanks for your interest.
I attach my httpd.conf. Please note that all the stuff included from other directories (conf.d, vhosts.d) has been disabled, I just include the vhost.conf from my previous comment and listen80.conf which is only a set of Listen XYZ:80 directives.
I also attach the list of currently loaded modules (mod cluster is now disabled)
Yes, I'd like to use mod_cluster for my tomcat/jboss apps and balancerMember for drupal.
Best.
Paolo
p.s.
sorry, I attached vhost.conf twice

> Hello,
> I'm experiencing an issue very similar to https://issues.jboss.org/browse/MODCLUSTER-356
> When I try to use a BalancerMember directive, I get a segmentation fault, caused at line https://github.com/modcluster/mod_cluster/blob/1.3.1.Final/native/mod_proxy_cluster/mod_proxy_cluster.c#L2223
> I tried to remove directives from the virtual host, but the issue persists until there is at least one ProxyPass using a balancer defined with BalancerMember. I attach a .conf file where I put all of the configurations involved in the issue and which is causing the crash.
> If I put a check at line 2223, there are no more segmentations, but a 503 caused by mod_proxy_cluster.c(2332): proxy: byrequests balancer FAILED
> Thanks,
> Paolo
