We've been getting these errors on our Channel Access Proxy Gateway for the last couple of days. We are using the version of the gateway built against patched EPICS 3.12. Use the gateway to provide access to the controls subnet from outside the control system. Only see these errors for two outside hosts. Other channel access through the gateway seems to work fine. I finally blocked access for the two hosts at our firewall. Had more than a Gig of log messages just like the following:

CAS: bad message type=11
CAS ? on ? at xxxxxx.yyyyyy.lanl.gov:5064: cmd=11 cid=4294967295 typ=0 cnt=0 psz=40 avail=8e
Internal failure - unexpected error processing stateless protocol


Can't find a match to any of the strings in the errors in the gateway code itself. Anyone have an idea about what they mean?
