we had a similar setup, but dropped it in favor of a single server,
basically because it was too hard to keep the list of disabled (blue)
services in sync. (The server is an ESX VM so unlikely to die anyway.)

Your problem is that you have two hobbitd_client processes running.
Both servers receive "client" reports and will decompile them into
separate disk/vm/... tests. The results are then also sent to the
other server.

You could try either to disable the hobbitd_client module on one
server, or remove the other server in each server's BBDISPLAYS
setting. Both approaches have their drawbacks, though.
