Your workers2.properties looks a little off. I don't know if this is the
root of your problem but it should look more like:
[shm]
file=${serverRoot}/logs/shm.file
size=1048576
[lb:lb_01]
info=Default load balancer.
debug=0
# Example socket channel, override port and host.
[channel.socket:localhost:8109]
info=Ajp13 forwarding over a TCP socket
tomcatId=worker1:8109
lb_factor=100
group=lb_01
# define the worker
[channel.socket:localhost:8209]
info=A second tomcat instance on a different port.
tomcatId=worker2:8209
lb_factor=100
group=lb_01
# Uri mapping
[uri:/*]
group=lb_01
debug=0
You have to adjust it to your own needs. You can change 'localhost' to
another IP or servername.
