What is the cause of these 'validate errors'

Well, I ran v7.6.6 for 48 hours (~3,300 tasks) - not a single error at my end, just one "can't validate" because too many wingmates failed, like in yesterday's screenshot.

Then I regressed to v7.6.3, and within an hour got another

Again, I captured both the screenshot and the contents of the orphaned stderr.txt - it was complete, unlike task 1191232622.

OK, I think that provides conclusive evidence of cause and effect - I think my work in this thread is done. Moving on to pastures new.

Before I go, BOINC v7.6.6 is now available via the Download All page.

Saw that. Thanks again Richard. I've asked for a sticky mentioning that fact and the benefits of running the new client, especially here at MilkyWay.

Howdy Folks,

Would those of you running 7.6.6 be willing to report test results to http://boinc.berkeley.edu/alpha/?

It would greatly help getting this build out the door for public consumption.

Thanks in advance.

I signed up for the alpha list as that is the first requirement. I read the instructions and it looks like you have to first delete your existing BOINC directory?? That can't be right, or is it.

took a look at my stats
new version is 7.6.6
In progress (48) · Validation pending (0) · Validation inconclusive (28) · Valid (21) · Invalid (4) · Error (2)
too much inconclusives and invalids&errors
reasons and ways to avoid it?

Inconclusives: that is a consequence of the way this project is configured, using Adaptive Replication. They will be validated eventually, and the number of tasks chosen for validation by wingmates will go down as the other errors reduce.

Invalids: the only invalid tasks showing on your account now are from 15 July or earlier, when you were using BOINC v7.6.2
