I attached file with dump of working tomcat.
My config is something like that:
worker.list=worker1,worker2,worker3,loadbalancer
# Common worker properties
worker.template.port=8009
worker.template.type=ajp13
worker.template.connection_pool_timeout=600
worker.template.socket_timeout=60
#worker.template.socket_timeout=120

# Set properties for worker1 by referencing worker templates above
# Connection to local Tomcat (Trade Client)
worker.worker1.reference=worker.template
worker.worker1.host=localhost
worker.worker1.connect_timeout=10000
worker.worker1.prepost_timeout=10000
# Set properties for worker2 and worker3 by referencing worker templates above
# Connection to remote JBOSS (ATE - Condico Clearing Station)
worker.worker2.reference=worker.template

worker.worker3.host=ate2
worker.worker3.lbfactor=1
# Load Balancer worker
worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=worker2,worker3
for now i dont know what log, or what information can be helpful.
