Absolutely correct,
I think that problem may be caused by the JBoss GC (stop the world)
activity.
When it occurs on HA Singleton MASTER node it makes the
web-applications not availables, and the node is considered "off-line"
for 1 minute by the apache.
No problem arises for "standard cluster a
Hi Roman,
my scenario is similar what you describe, but whit a little difference:
I have one or more contexts served by all of the nodes in the cluster,
and another contexts served only by the Master node.
The Master node manages the contexts deployed in HA Singleton.
Only one Master node is act
Federico,
503 would be due to a node being not responsive, you can configure your cluster
to disable a node after one or more failures with mod_cluster. now back to
mod_proxy_balancer and mod_proxy, if i understand correctly, you have a
scenario where you have one or more contexts served by all

Hi Roman,
the mod_cluster is what we have actually in production.
I want to change it, because the communication
between Jboss and front-end sometimes fails with error 503.
I would like to use ProxyPass in order to investigate if these kinds
of errors will remain.

Federico,
since you are using JBoss, i would suggest to look into mod_cluster instead.

Hi Eric,
thanks for the hint but I think it's not what I need.
Defining the standby node(s) in the balancer definition I might loss
functionality for these reasons:
- the JBoss cluster has both web applications deployed in HA Singleton

Hi,
I've an Apache/2.2.15 in front a JBoss Cluster (based on 2 nodes)
in which web applications are deployed in HA Singleton mode.
In this case the web applications are always running on a specific node
but/and in case of failure the cluster actives them on the other node.
I'd like use Apache Pr
