Repeating message in log

[lemrock]

All of a sudden my HABridge is slowing down and I'm getting this message over and over "The requested route [/(null)] has not been mapped in Spark for Accept: [null]". Hundreds of these messages are listed in the log. Any idea what's going on here? I'm using ver 5.1.0. Here is a sample so you can see how often this message logs:
