The last time this happened there was some sort of system problem. Anyone else having computational errors? ID: 2092 · Rating: 0 · rate: / Reply Quote

Same here but with me it started following a Win 10 update. Coincidence? Yes because it's happening on Linux machines too, it's being caused by the Project sending out files that are empty ie nothing to process inside them. However some units are getting thru that work just fine so you can either switch to another Project for a bit or keep going thru them. ID: 2094 · Rating: 0 · rate: / Reply Quote

It appears to be a coincidence, as this problem has been affecting a variety of my Macs, running MacOS 10.11 - 10.14. The good news is that the problem is dissipating, as my RAC is beginning to rebound. My individual Macs are recovering at different rates. This is probably due to the fact that I have not standardized my Collatz task cache across my machines; some have as few as 2 days of work, whereas others have as many as 10 days of work. So, the cache of affected tasks is being cleared at different rates. ID: 2097 · Rating: 0 · rate: / Reply Quote

Hey, Mikey, I see that you have increased your hardware commitment to Collatz. Your RAC is more than 40M/day - very impressive! I may have to perform some more upgrades to stay in front of you - I have an RX580 that has yet to find a home! ID: 2098 · Rating: 0 · rate: / Reply Quote

I got 2 new for me gpu's acouple weeks ago and decided to see what I can do if I mostly focus on a gpu project. I'm also earning GridCoins right now so it makes sense to focus a bit on a project.

My 1080 was crunching just fine until a few days ago and now I have over 1200 failed tasks. I was unable to determine what was wrong, so hope it clears up with newly generated work. Thanks all!

Likewise, many errors after 1-2 seconds. I think it's starting to end, the problem is fileswith no data in them, andmost of my gpu's are now processing files with data in them, I'm still getting some blankones though.i don't know if they are resends or new ones though.

Good point. Each failing file will get tried 6 times before it is flagged as an error. My failures are becoming less frequent, and those that do fail are now on their fifth or sixth attempt.

The batch that I received before that with deadline 12/7/19 15:16 was better with 'just' every 7th or 8th job in error. Now that rig has a project backoff 23 hours so it's more or less banned because of all errors. ID: 2114 · Rating: 0 · rate: / Reply Quote

Looks like the affected batch was generated on November 17th. ID: 2115 · Rating: 0 · rate: / Reply Quote

YES the problem is the units were being sent out with blank files, once they are all gone thru though everything should be back to normal again.I have 835 workunits in progress right now so we are going thru them!! I also have 3844 workunits that have had errors, before this started I had less than10!! The max number of errors for each workunit is 6 and today I saw a bunch of _4 and a few _2 at the end of the tasks that had problems, since it starts at _0 we ARE getting there.
