RE: Since a few days I have

Quote:

Since a few days I have an increasing number of taks, that ends up with "Error while computing" after run times shortly under 300[s]. So my last 8 tasks today. These tasks became donwnloaded about 5,5 days before. But a few files are running nicely.

Kind regards

Hi

I checked some of them and the problem seems to be related to diskspace

Thankyou for your work.
But I don´t understand this, as E@H uses at most 9GB, in the mean about 8.5GB of discspace but available are 15GB and 31 GB are free on the partition. So this should not be the problem, as far as I know. The CPU has 8GB of RAM available, but uses 3.5GB only, as seen in the taskmanager.
All other tasks are running well.
Do you have some suggestions?

Kind regards
Martin

There are three criteria that

There are three criteria that limit diskspace used. If you hit that limit with one of them you will see that message even if the limit isn't reached according to the other two criteria. As far as I know it works like that.

If for example you trigger the maximum percentage of total diskspace Boinc is allowed to use, it doesn't matter that Boinc is allowed to use 15 GB for one of the other two criteria.

I'd suggest you carefully review those three criteria.

I checked this, but all seems to be set suitable.

Peculiar in the according remark in the event log is, that it shows MB instead of GB. But if it would be GB instead of MB either value would be larger than my limits.
So I increased my limits for diskspace. Let´s wait what happens.

Kind regards

Do you have more than one

Do you have more than one BOINC project enabled? I've found that some BOINC versions assume that the allowed disk space must be divided equally among the various BOINC projects your computer is attached to, even if some of them use nowhere near that much disk space.

Hi This could be related

Hi

This could be related to the per task disk limit. I'm not quite sure why the limit could be triggered at your PC but not on others. I suspect tho that the BOINC version you are using is maybe doing the accounting a bit differently. Still, this is something that Bernd will want to look at.

Thanks for the report.

It's no longer triggered on

It's no longer triggered on any of my PCs, but I'm not sure if that's because I have since upgraded to a newer BOINC version (now 6.12.34) or because I have increased the disk space limits on all of these computers.
