Please correct me if I am wrong, but the topic title  fibs message appears more often for 3dfibs, right?
My only workaround I found for it was a log off followed by loggin on again, and that solved the problem. Otherwise , fibs kept throwing me out randomly.
Patti? 
Maareyes?

I haven't received this message in Javafibs command window for as long as I recall. Is it maybe only because 3dfibs has a few issues regarding the connection/to/fibs part?
I also didn't saw this message in the 3dfibs command window for every version, in each version of windows I have used. Could it be that whenever an automatic update of the OS is installed it screws up 3dfibs?
I am not expecting solutions, just answers here.
