There's a News item about the problem, based on an email from Andy.

The credit script is only running once a week at the weekend now so some time on Sunday you should see credit.

Yup, similar problems here.

The trickles were missing a week or two back, and then appeared "recently". Along with a BOINCstats update.
And they now seem to be missing again, in the last couple of days.

There are some comments about this in other threads.

Workunit 10114084 still running and upto 8.731% with no problems yet, trickle sent.
My other laptop has Workunits 10115351 and 10115880 running, both up to about 2.9%. No trickles sent from those ones yet.

Seems to have just been the first couple workunits that had the zip problem. But there's still a lot of data to be crunched yet.

We can't see your computer names. so we'll have to guess which is which. But I see that all computers on your account have been upgraded to Windows 10 - this might possibly be significant. The project staff are going to check in the morning whether there is a significant correlation across the database between running Windows 10 and these new task failures.

There are a lot of files that are reusable.

The folders (with files), that can be deleted, are the folders for the models. These will have a 4 letter code name, similar to those that are currently running.
They're mostly the hadcm3s models, and any of any type that crash.

Note down the 4 letter code of all running models, and delete those that aren't among them.

This is a known problem. Some of the hadCM3s don�t clean up after themselves even when they finish normally. There is nothing to do about it except check the ProgramData folder occasionally for left-overs and clean them out.

Has anyone else noticed that the models seem to be taking about twice as long to run with Windows 10 as they did with Win7. Hadcm3s WU�s that took about 43 hours to complete running Win7, seem to be taking about 90 hours under Win10 on the same machine.
