liferay feasability to use Mod_cluster instead of mod_jk for load bancing

Dear Liferay Experts,

We are facing issue in load balancing, we are using mod_jk for load balancing, some times garbage collection is happening in the liferay nodes and it is utilizing high cpu, memory @ this time liferay server will become unresponsive but the apache nodes are still sending request to this unresponsive nodes we didn't find any inbuilt support to handle this in mod_jk , so we are planning to implement mod_cluster but I would like to know is it good to go for mod_cluster will liferay support this or we have any alternative to handle this.We are using Liferay 6.2 along with Jboss-eap-6.1.

kindly provide some suggetions how we can handle this scenario.

Thanks & Regards,
Iqbal

If garbage collection time was my problem, I'd rather tune garbage collection instead of changing the connector to the webserver. I might be missing a point here, but it sounds counterintuitive to me.
