Ok. So I just saw an error come in at around 11:11:32

I then did a grep for "orphaned" and it appears to be happening often but not enough to trigger an alert.

I understand that there are newer versions elsewhere but I am looking for the supported version by nagios.

Orphaned hosts could be a Hostgroup settings in the Modgearman configuration files.
If the Gearman server tries to run the host check on the wrong gearman worker, it could generate that error.
Another cause is if the Nagios server or the Gearman server / worker cannot process the checks quick enough because of resource issues, could cause that error.
Make sure you have enough CPU's and Memory assigned to the servers.

One thing to try is to edit the Gearman worker config files and increase the min workers and max jobs, that could solve the issue as the worker can process more checks.

I have not configured Hostgroup settings in modgearman.
Our DR server is checking 9 Hosts with a total of 65 services. It is a physical server, 128G RAM, and CPU

Architecture: x86_64

Has gearman worker with setting set to 10 workers and max jobs set to 1000.

Any other ideas?

Check all of the logs for all of the workers and see if there is any errors in them that could help.
Does the DR system have it's own Gearman Infrastructure or is it sharing it with others?

the DR server only has the worker on it and the server on it. It is stand alone manual DR.

I enabled debug on the gearman worker as well as the server. Only the server reports orphaneded checks and they are only for hosts, not services.

Can you post the full worker.conf file and the module.conf file and the output of the following command run on the Nagios server?

I PMd you the items.

tgriep is actually out this week - can you please post the items or send them to myself in a PM? I will be sure to share the items with the rest of the team.
