Depends how you printed the error.
(From memory: if you use rtapi_print then they end up in dmesg, if you use 
report_error they surely end up at the HMI).
The problem with the Error NML channel, is that it can only hold so many 
errors, if they come in a burst and the GUI doesn't read them all out, the 
queue will overfill. I think that will happen independently of how large the 
queue is.

Donnie: maybe try really increasing the queue lenght in the emc.nml file in 
your config dir.
(like 20-30 times as big, maybe even more).
