Instead of being an idiot, be informative and post a link or a quote.

I gave you the answer, straight into your hand. And you still weren't able to figure it out.
(I agree that information is hard to find sometimes - that is why you should look at the topics first. If you don't have time, I don't think you can expect someone else to do it for you.)

What you said was it has "something" to do with "decemeber 25"
Well what exactly is something? and what does decemeber 25 have to with anything when this problem goes back to the 18th or even earlier?

If you have time..go find a specific post and put the link here.
I do that for people when I have time and know the specific answer from another post.
Generalization does nothing for me. That's what you offered. "Something"

Here is specific detailed info that I see on my single project graph.
All other projects are 100% equal share with Rosetta. (default setting) Rosetta is losing credits and should be trying to make them up but does not. Credit stays normal until on the 17th and dips for a day and the corrects itself until the 21st and after that all downhill. So how does this go with your "something on the 25th"? 17 and 21 predate the 25th.

Amazing!!

I am seeing all too many errors from work units at the end of their processing cycle (after 12hours processing) and would like some advice as to whether there are any changes I can make to stop them.

Examples can be seen in WUs 1062692421 and 1062687362 but basically they show exit status 139 (unknown error) with signal 11 and a message saying that default.out.gz already exists with size -1.

Any suggestions would be gratefully received.

You may need more memory. You have 8 GB on your Ryzen, but the Rosetta work units sometimes take up to 1 GB each.

Ouch, I know my free memory sometimes goes down to 2 or 3% but I hadn’t thought of it going negative.

Thanks for the suggestion, I’ll look at getting another 8gb and maybe some more for the FX rig as well, that only has 4gb for the 4 cores.

Hmm, that raises a thought. They’re both running half and half between Rosetta and WCG which, I think, has a lower memory requirement?

Yes, all the WCG ones that I know of have a pretty small memory requirement. The biggest is MIP, which is around 300 MB.
But you probably aren't always running an equal proportion of Rosetta and WCG. The BOINC scheduler does strange things, and may give you all Rosetta once in a while.

You might check if decreasing the time that workunits can run on your computers to ten hours has any effect on this.

The time was set to the default of 8 hours so I don’t know why these were taking 12 hours anyway but I reset it to 6 hours yesterday to try to reduce the loss when a wu errored out in this way.

I monitor them fairly closely and I’m fairly sure the the ryzen was running 6 and 6 at the time. The FX had just come out of a period where it was running all Rosetta for a few days to catch up after running all WCG for a while but the ryzen completed 46 WCG WUs that day which is about normal and was equal every time I looked.

OK, extra memory ordered for both machines so we’ll see if that sorts it.

Whilst I’m here, a silly question if I may.

Is there any way of changing the View Tasks page from sorting by date sent to sorting by date returned?

I take it you are asking about the website? ...and not the BOINC Manager tasks page. I am not aware of a way to define how to present the web page.

Ok, thanks. It was worth asking :-)

OK, extra memory ordered for both machines so we’ll see if that sorts it.

It seems like Rosetta gets into a state where it consumes 1gb+ per WU. I am running 35 WU and there is always a couple taking over a gb.

I watch the difference between CPU and RUN times and swap used. As long as the swap used is very low, you are probably not running into memory problems. I tend to buy more GB of memory than threads. I originally got my 36 thread machine with 32GB and that was not enough. You can see that 19gb of my swap space has been used even though the machine has 64gb installed for the 36 threads. 19gb swap space used is concerning.

Based on over a thousand jobs each, the credit difference between the 64-bit Rosetta WU and Minirosetta 32-bit WU is negligible. 44.0 credits/CPU hr for Rosetta 4.08 and 45.7 credits/CPU hr.

19gb swap space used is concerning.

19 GB would indeed be a lot of swap in use but haven't you got the unit wrong? It looks like 19 MB to me.

Sorry to be a bit late on this, but I did notice around 13th March I had a task consuming 2.4Gb and 14Gb of my 16Gb (total) RAM being in use to run 8 tasks.

I can't recall the tasks involved. Right now I'm back to my more usual level of 7.74Gb in use

DOH! You are obviously correct. I got units of GB dancing in my head.

As of this AM I have 16gb on the ryzen and it's currently showing 81% free memory but that's with no Rosetta as no WUs have come down since early yesterday.

I'll monitor going forward and report back.

Yes, we are back to 8086 tasks ready to send according to the server status page which actually means 0 tasks ready to send. Maybe the admins should investigate, what those 8086 tasks are and if they eventually cause the issues.
