Yes, we have. They are fine.

I'm seeing "failure to join the cluster" messages prior to the  
"network unreachable" in the mmfslog files, so I'm starting to suspect  
minor disparities between older releases of 3.5.x.x at one end and  
newer 4.1.x.x at the other. I'll dig a little more and report the  
findings.

Thanks
