Almost every day I get these bogus Notices:

Lies.
Rig-45 has 338 GB available on its SSD with 22.5 GiB used of 31.1 GiB RAM and a barely used 16 GiB swap file.
Rig-17 has 89 GB available on its SSD with 23.9 GiB used of 31.1 GiB RAM and a barely used 16 GiB swap file.
Rig-36 has 774 GB available on its SSD with 22 GiB used of 31 GiB RAM and a barely used 16 GiB swap file.
Just another bug that I doubt will ever get fixed since nobody with the power to fix it even cares enough to read these forums.

This board is monitored by moderators, who pass on to the project people anything that they need to know.

With your computers hidden, and not much info in your posts, I have no reason for a message to them.
It seems more like a problem with the way space is allocated and/or permissions for some part(s) of your systems.

Where do those notices appear? I do not recall ever seeing one like that OTOH, I have a lot of disk space (an entire partition) available to Boinc, so I probably am not getting any. Over 80 GBytes unused and available for Boinc. I looked in the Event Log and see nothing like that.

If there was an easy way to post a screenshot I'd show you pictures. I use BoincTasks and they appear in the Notices tab and also the Messages tab. It's been a long time since I've seen one these messages but when the CP servers go down for days on end and I've got a growing list of completed WUs and Computational Error failures that cannot upload these messages appear. I have no shortage of memory. But this status causes other projects to stop sending work:

1649	World Community Grid	9/27/2021 7:57:34 AM	Message from server: OpenPandemics - COVID 19 needs 200.00MB more disk space.  You currently have 0.00 MB available and it needs 200.00 MB.	
1650	World Community Grid	9/27/2021 7:57:34 AM	Message from server: Mapping Cancer Markers needs 500.00MB more disk space.  You currently have 0.00 MB available and it needs 500.00 MB.	
1651	World Community Grid	9/27/2021 7:57:34 AM	No tasks are available for the applications you have selected.

I've even tried suspending all WUs at checkpoints and rebooting the computer. This problem is caused by CP and only the computers running CP WUs have this problem.

Hmm, not sure how you got this. My computers are headless and when I remote into them and try to launch the BoincManager it almost always says Disconnected and getting it to connect is a chore. Is there a file in the BOINC folder that includes those data???
I looked in the client_state file but CP reports so little. Here's what WCG reports on start up:

I switched to Open Toga Policy. Start with Rig-36 as it's the worst offender: https://www.cpdn.org/show_host_detail.php?hostid=1521343
The problem is not with my computer it's with the faulty CP code.

Which staff would that be?

Staff implies employment implies pay rather than volunteers using their spare time trying to help you.

I looked at the 1st 6 computers on your list, and none of them have anywhere near enough memory to run so many climate models at a time.

The UK Meteorological Office wrote, owns, and maintains the climate models.
They normally run on their supercomputers, and their biggest user is the military. We're just small potatoes in their use.

The problem is not with my computer it's with the faulty CP code.

You may be right but even then, given that as far as I know this exact problem hasn't appeared before, that implies there is something about your setup that triggers the problem. I like Les, have been crunching since the early days of the project and not encountered it either personally or on the message boards until now.

I just checked the system requirements page and the page has clearly needed an update for a long time! I would suggest a minimum of 2GB/core and that will likely go up further when the mythical Openifs tasks appear. (I have 32GB for a 16 core (8 real ones) machine and am regretting not getting double that.

Do I misunderstand something, or is something else wrong? The original post shows complaints that the O.P. does not have enough DISK SPACE. And the responses seem to be about the amount of RAM needed.

1. The computer may be crashing lots of tasks which are not being cleared out, thus slowly taking up disk space.
2. If the computer is being allowed to continue running tasks while the re-cabling of Oxford is being done and we're "off the air", then it will also fill up with files waiting to be sent back.

Yes. The people with the power to actually fix bugs and adjust server settings to behave properly.

Where does it say how much memory is required to run these WUs??? Why don't any of my computers report any shortage of memory of any kind??? Can you be specific please?

Ok, the mystery deepens. If only ten hadm4h (the only WU causing this problem) needs 2 GB/WU then 20 GB of RAM should be enough. I have 32 GB of RAM and it's not enough???
If this is right then I'll suspend at the next checkpoint and double my RAM to 64 GB and the problem should go away. Right? Let's see.
