[Openmcl-devel] CCL thinks buffer exist...

[Gail Zacharias]

I've seen this happen as well, but I haven't been able to figure out 
how to reproduce it.  I assume the problem happened at some point 
before the error, where a listener was somehow incompletely created 
(or perhaps incompletely killed?), and now different parts of the 
system have different views on whether it exists or not.  Once it 
happens it will keep happening in that image.  It would probably be 
possible to patch around the symptom, but it would be nice to figure 
out what the actual bug is.  Any idea what you did _before_ it first happened?
