MD5(Unix) bug

[infinity432]

I'm having a weird issue with the Unix MD5 hash type. After about two minutes of running, one GPU completely drops out, and the other that continues seems to not be processing correctly.

Also, when I attempt to quit using "q" after this happens, the process hangs and ultimately becomes zombied. I only seem to have an issue with this hash type, the others I've tested seem to work fine.

Thanks for the help in advance.
