My client got stuck downloading a CPU work unit on 25may & hasn't loaded any since. GPU work units are still downloading & finishing OK. Here's part of the log:

Don't use the CPU 11 setting. Fah excludes prime numbers. Try 12 or 10.

It seems to have hung during a download. Try pause and unpause for the slot. If that doesn't work, restart the client. (The easiest way to do that may be to reboot the PC. Other ways exist but are OS dependant.)

@davidcoton: Thanks, rebooting got it going again.

@7im: Thanks for the reply & help, but I've always been using the CPU 11 setting. The Fah installer set that & I didn't change it. My involvement with the Fah software is minimalist - I don't tinker with it, just installed it & let it run as much as possible.

The client has a known problem when there is a communications error during a download or upload ... it never recovers without a reboot. We do hope that this will be fixed in a future version of the client but for now, a reboot (or a restart of FAHClient) is the only answer.

The problem of Gromacs failing when using 11 CPUs is also known, but I think you'll find that the software altered that value. The FAHCore actually uses 10, even when it's set to 11, avoiding that problem.
