Maybe it was your crunch command line that was bad, I'm not familiar 
with crunch.

Anyway I would use latest bleeding-jumbo from GitHub with mask mode. You 
don't need crunch and MPI is better replaced with -fork for a single host.

For the pattern you describe it will be like:

	./john passwd -fork=8 -mask=?d?d?l?l?l?l?d?d

I cracked your password in 49 seconds using the above command line.
