I don't understand that either but have been bitten by this problem more 
that I would like to say. It's annoying and maybe it has something to do 
with AFS. But if the token expired (which likely it did) it shouldn;y have 
vene created a zero length file. It's very exasperating.

The defintive place where the core file is supposed to get created can be 
determined by 'lsof -p <pid>' for the process and looking for CWD. I think 
I will add a message to the log explicitly saying what the current working 
directory is as this seems to be a point of confusion.
