Having recently returned from vacation I'm trying to resume processing Rosetta tasks. One PC has found work to do immediately, the other hasn't.

The BOINC Manager Event Log shows that the bored system is requesting work:

3/18/2013 3:03:55 PM | rosetta@home | Sending scheduler request: To fetch work.
3/18/2013 3:03:55 PM | rosetta@home | Requesting new tasks for NVIDIA GPU
3/18/2013 3:03:57 PM | rosetta@home | Scheduler request completed: got 0 new tasks
3/18/2013 3:20:10 PM | rosetta@home | Sending scheduler request: To fetch work.
3/18/2013 3:20:10 PM | rosetta@home | Requesting new tasks for CPU
3/18/2013 3:20:12 PM | rosetta@home | Scheduler request completed: got 0 new tasks
3/18/2013 3:20:12 PM | rosetta@home | No work sent

The Rosetta Computer summary page for the host (https://boinc.bakerlab.org/rosetta/show_host_detail.php?hostid=1430484) shows that the host keeps contacting the server. The Rosetta home and Server Status pages appear to show plenty of jobs waiting. The BOINC Manager project Update and Reset project commands haven't helped. The project is neither suspended nor set to not request new tasks.

Any troubleshooting suggestions? Or a link to the sticky "Troubleshooting - Not Getting New Tasks" topic?

One idea would be to go onto THAT pc ONLY and click Reset Project in the Boinc Manager under the projects tab. That should redownload all the project files and essentially start you over, but without forcing you to log in again.

Maybe there is not enough free space on your working partition?

We have a winner! Thanks slicedbread. The >100GB of underwater photographs taken on vacation didn't leave enough free space. A little housecleaning fixed things. I would have expected BOINC to get work, but not run the tasks, if there was insufficient space. Or at least note the problem in the Event Log.

mikey: As shown in the original post, I did try both Update and Reset project in BOINC Manager. They requested tasks, but none were downloaded.

Looks like another opportunity to improve the diagnostics in BOINC.

This information should come from the server, however Rosetta is known not to send any useful information when not sending tasks, which is indeed very annoying. After all, the server knows why it didn't assign any work, why shall the user need to figure that out by himself if he could just get the info from the server?

Rosetta must be using a very old server version then, most projects do let you know, although as you said it can still be a bit cryptic, but the message will say something like 'insufficient disk space' or something like that. I looked for that and when I didn't see it decided it can't be that. Oh well, I am glad it is working again!
