Hi all,

I'm seeing an issue in BOINC where all the tasks related to the World Community Grid project just hang, and make no progress at all anymore.
The "spent time" and "remaining time" keep counting, but the progress bars for each task is definitely stuck.
What trickles me, is that the tasks are still running on the CPU. I would get if they are suspended for any reason, but that's not the case.

See the log for reference:

First set of problem I see STARTS HERE:
1) "29/11/2016 16:11:19 | | Disk: 79.44 GB total, 5.31 GB free"
...
2) "29/11/2016 16:11:19 | | Reading preferences override file"
....
3) "29/11/2016 16:11:20 | | max disk usage: 2.00GB"

4) "29/11/2016 16:39:45 | rosetta@home | Rosetta Mini needs 276.64MB more disk space. You currently have 677.03 MB available and it needs 953.67 MB."

Your computer will NEVER be able to process ANY work from just about EVERY project you are attached to because:
1) The total available disk space to BOINC is 5.31 GB.

2) You have RESTRICTED BOINC (in a LOCAL MANUAL OVERRIDE setting) to a MAXIMUM DISK SPACE of 2GB.

SOLUTION:
1) You need to free up some space on the hard drive for BOINC to be able to download the project run-time, data files, etc and it needs MORE space to store and run the various project temporary files.

2) INCREASE the max disk usage to 10 or 20 GB in your local preference override if you want to run any BOINC projects ever. BOINC CAN NOT RUN WITH ONLY 2 GB of USABLE DISK SPACE.

WCG & Rosetta can be very greedy when it comes to disk space, so that may be part of the problem. But if progress is being stalled, at least on the display you have two separate issues going on.

Have you tired using the "advanced" view rather than the normal view. The advanced view gives more details about the tasks running, elapsed time and progress, without the fancy graphics which can clog things up a bit.
