I'll have to test this myself as I do a backup of:

That particular message is only reported the first time it is encountered.  
In my case it is at emc startup almost instantly on AXIS drawing the logo's 
backplot, but only about 25% of the time.  So obviously you are not seeing 
that, then but later.

So I'll make it a point to leave it running after a clean restart, then 
check the next morning to see if it has been reported.  FWIW, if I get a 
clean start, the only thing I've noted that will cause that error later, is 
to fire up some kde-based gfx utility such as kaffeine.  As I often have a 
screen with FF running, and a 3rd screen with Konversation running, I have 
not noted that either of those can trigger it on my machine.

I found the kaffeine trigger while running the latency-test which had at 
that point been returning about a 10 u-sec figure max & started an 
installed but useless program since I don't have a tv card in that box, but 
the kaffeine startup caused a 400 u-sec latency.  I assume there would be 
others just as bad on my box/video card.

In my use of FF & konversation, I don't switch off the emc screen unless it 
is halted/paused, because I have never rigged a manual e-stop, and when on 
some other screen, the esc focus is not relayed to emc.

Don't ask me how I know that, or how many bits broken or clamps cut into. I 
do learn eventually though.  :)

As of tonight at about 5:30P, emc had not reported an Unexpected Realtime 
Error.  emc, ff, and konversation were all left running.  But that also is 
only one amanda run, so I left it running for another night.
