Hope this helps someone else in the future.
After much testing and comparing: It seems that before you can use the 0.0.0.0 entries, you must have the actual host entry with the IP Address on the line in bb-hosts. It must be declared FIRST (before any of the 0.0.0.0 entries) in the bb-hosts file.
GOOD:
128.192.10.10 device.abc.com # comm
group-compress aaa ...
0.0.0.0 device.abc.com
. . .
group-compress bbb ...
0.0.0.0 device.abc.comBAD:
group-compress aaa ...
0.0.0.0 device.abc.com
128.192.10.10 device.abc.com # comm.
group-compress bbb ...
0.0.0.0 device.abc.comI automatically generate list for the Windows Admins with all of their servers listed below their name ICON. This way the Admins can keep up just their list of servers. The script runs every day early in the morning. I have up to 5 - 0.0.0.0 occurrences in the bb-hosts file.

Only the device with an IP address is tested. The 0.0.0.0 entries are so that you can show the tests on other web pages in xymon. I do this on over 100 devices so the 0.0.0.0 entries should not be causing the problem.
I am still at a loss where it is getting the message. I should be able to have one actual test entry with the IP address on the line and Multiple 0.0.0.0 entries that are associated with it. Why is just this one entry having a problem????
Do I have to remove all the entries for this hosts including the Xymon DB entry and add them back in again?

I cannot find a second entry with an IP address.
I have hundreds of other servers with 0.0.0.0 entries so I cannot
figure
out what is happening?
Since case isn't relevant in hostnames, I'd say the error message isn't strictly correct: cswflex4.csw.l-3com.com actually appears four times in bb-hosts, not two. As indicated by the error, this may cause strange results.
I'm not sure what your point is about the 0.0.0.0 ip. With no TESTIP tag, the ip will only be used if hostname lookup fails. And used or not used, you have four instances of the hostname in bb-hosts, which can give strange results.
Or maybe I'm not reading your post correctly.
