SMP work servers in yo-yo mode? [No, try client upgrade]

[hyphessobrycon]

I'm not consistently able to get WUs for my SMP machine. Sometimes, it'll pick up another one immediately on completing one, and other times, hours will go by before it gets one. The log looks as expected:

Code: Select all

...etc. Anybody else seeing this?

Can you post details on your client? Have you upgraded to v7 yet or 6.33+? If you're still using a 6.2x client, that may be the problem.

Oh... Yeah, I have an old client, one of the 6.x series. I'll upgrade and see if that helps.

Many thanks!

Supporting Kasson's statements, Dr. Pande's blog post mentioned this: http://folding.typepad.com/news/2011/11 ... a-fix.html

Yup, that was it. I picked up the 7.1.38 client, and it started chugging away immediately.

Thanks to you both!

That is a bit of a problem for people running on older Macs. I have a server running OS X 10.5.8, which can't be updated. The v7 clients require OS X 10.6.4 or later, and v6.33 isn't available for OS X yet. Luckily my main folding machines can (are are) using v7, but some of the old ones are going to be out of commission for a while it sounds like.
