I'm completely new to the Folding@home so I may misunderstand something.
I've installed and run the client about 3 hours ago. It seems to have successfully downloaded and processed the first portion of data, but after finishing it and uploading the results it fails to start the next portion.
The log says:

What's the reason of such a behavior?
Is there anything wrong with my client?
I don't think it pertains to my computer, but just in case it's

When you have delivered a job, the client send a query for the next one, but you only get one if there is one available for your specific hardware, which is not always the case right now, as the servers are not able to generate enough jobs (WUs) for everybody. See: viewtopic.php?f=2&t=33193
Solutions are in the work and everyone hopes that it will get better soon. Until then, please be patient: your client will resume crunching automatically when jobs are available.

I see. Thanks!

Yet I can't comprehend the situation with the client. After restarting, it had downloaded and processed successfully a few WUs, and then it stopped again. It unsuccessfully tried to get an assignment several times, then seems like gave it up and had been standing idle for several hours or half a day, without even trying to get a new assignment. The log says

No new lines after the last one ("Connecting to 18.218.241.186:80") appeared for hours.
I saw no evidence of the client's activity.
After restarting it began to work normally at once.
This makes me doubt that the client can automatically get a new WU and continue working after having been waiting for WUs for several hours. How can I clear up this issue?

The client retries are programmed to get longer to not exacerbate the load issues on the server - the behaviour you describe is consistent with that ... Restarting the client restarts the retry timer - but an easier way is to pause the slot (or whole client if you only use one folding slot) wait for a minute or two (the log will should a batch of line showing a configuration refresh) the set the slot back to folding.

The team have ask people not to use the pause/folding too often (you can see the retry time in the advanced control - maybe do this when it gets over an hour) as it just makes the loading on the servers ... If you use the forum search function you will find many discussions and better/clearer explanations ... but the upshot is there are times when the severs are too overloaded to hand your system a WU and this is what you are seeing.

I got it, thank you!
