I thought I could write this up quickly but I have to leave, I'll update this sometime tomorrow with more information.
The gist is that I don't think multiprotocol decoding is working properly, trying msgtype=scm and msgtype=r900bcd separately results in a much higher message rate than together. Also, It looks like maybe msgtype=scm,r900bcd produces different behavior than msgtype=r900bcd,scm.
