Thanks. Probably makes more sense if you tar/zip the whole `logs` 
directory as it's probably a combination of multiple of them what is 
going to give the answer. As sending attachment to this mailing list 
won't work, probably you want to upload the archive to the dropbox or 
smth like this

Cheers!
