Yep, I dislike mine so much I'm going to buy another one for the new DAW. I'm just a glutton for punishment.  
 
Bad RME bad!
 
Regards,

Although not quite the same I've got a Fireface UCX. Its connected on a USB3 port onto the motherboard but I don't get these messages at all (well, not so far :D ).
 
Been a while since I've checked for updated drivers, I'll have a nosey just out of principle :)

I'm using a UFX via USB, and I used a FF800 before that. I get that message all the time.
 
I haven't rigorously tested it to be sure, but it seems to happen when bit depth or sample frequency change. That is, if I'm working on a project in 96/24 and switch to 48/24 or 44.1/16, there's a pause, some clicks, and often the message appears.
 
I'm using the latest drivers and firmware.

I have a UFX running via USB and used to get that message back during Sonar X2 & X2a along with the early versions of the UFX driver (I purchased it when it first came out).  For me, it usually had to do with playing back / opening a project that was at a different bit depth or sample rate than my existing UFX driver settings were configured for.  It went away once i installed X2c patches & newer UFX drivers.
 
Have you checked to ensure your bit depth / sample rate settings match within the RME driver & Sonar?

I haven't seen the connect message since I have updated the drivers.  I have seen the render audio issue though. That is a random error with no explanation.
