You will need one worker per host:port thus in your case 4 of them not 2.

You only have contract for two instances. The latest one will overwrite the 
first setting.

Thanks for the quick response  TM

Okay so I broke them up and created another lb group (not sure if I had to do 
that) it looks like this

worker.list=part, myxx
#worker.list=worker1, worker2

#
# Defining a worker named ajp13w and of type ajp13
# Note that the name and the type do not have to match.
#
worker.jvm1.type=ajp13
worker.jvm1.host=10.17.75.145
worker.jvm1.port=8019
worker.jvm1.lbfactor=10

worker.jvm2.type=ajp13
worker.jvm2.host=10.17.75.145
worker.jvm2.port=8029
worker.jvm2.lbfactor=10

worker.jvm3.type=ajp13
worker.jvm3.host=10.17.75.61
worker.jvm3.port=8019
worker.jvm3.lbfactor=10

worker.jvm4.type=ajp13
worker.jvm4.host=10.17.75.61
worker.jvm4.port=8029
worker.jvm4.lbfactor=10

worker.part.type=lb
worker.part.balance_workers=jvm1,jvm2
worker.part.sticky_session=1

worker.myxx.type=lb
worker.myxx.balance_workers=jvm3,jvm4
worker.myxx.sticky_session=1

But I get the below error  in the mod_jk.log
 
[Tue Mar 20 15:32:10.978 2012] [27476:35628] [error] jk_worker.c (151): factory 
for lb failed for myxx
[Tue Mar 20 15:32:10.978 2012] [27476:35628] [error] jk_worker.c (262): failed 
to create worker myxx

I looked online and through my Apache Tomcat book but I haven't been able to 
fine anything when it comes to running two instances and on the same box 
sharing the same IP addresses on multiple ports.  I don't even know if I really 
need to make this change.  I don't think this option will work because jvm3 and 
jvm4 aren't defined in the server.xml files on the tomcat side

Thanks,
Martin
