It will probably be amongst the oldest ones. Don't forget the matching 
qf files too!
Make a tar file of a bundle of all the oldest ones. ('ls -tr | head 
-100' will give you the 100 oldest files, then you just need to make 
sure you have the qf and df for each of these messages, the "-t" means 
"sort by date" and the "-r" means "oldest first").
Send me as many as you like, I can soon find the troublesome ones in there,

Just give me the lot.

No problem. Once I have isolated the problem, I can put out an update 
that fixes the problem.
