No WUs available for this configuration

Greetings.

My FAH client is not getting any assignments. The error message is "No WUs available for this configuration"

I had a similar problem a year ago, and I was told it was an issue with "vav19" , which apparently doesn't exist any more, so I'm not sure where / how to ask for help or troubleshoot.

Is my machine just too old to be useful (to FAH) any more?

Here is the log from my most recent attempt.

Code: Select all

FAH requires minimum 3 CPU threads to be able to receive any work.
You are using 2 only for some reason. Your CPU seems to have 8 threads

Thank you very much.

For some reason, I had

Code: Select all

  <!-- Folding Slots -->
  <slot id='0' type='CPU'>
    <cpus v='8'/>
  </slot>
in my config.xml . Once I changed it to 8, it looks like I downloaded a work unit.
