I started three computers on this project and two are working just fine. The third, with computer ID: 5522, keeps getting marked "Completed, marked as invalid".

This is a partial list of the stderr out:

Can someone explain what is going on here and if there is anything I should be doing my end to fix the problem. This computer is running several projects and only CPU WUs.

This machine (ID: 5522) is still producing the same result for all work units. If anyone out there has any idea I would appreciate hearing from you. In the mean time I will just disable this project on this machine and try to get some of my other machines running the latest version of BOINC to get them involved.

I am a little disappointed that no one from the project can offer any insight into this problem if they have even looked at this post.

i have 2 macs and 2 raspberry pi's and 2 android phones all crunching for wuprop successfully
my new linux mint box returns validation errors on all tasks.

it has a brand new boinc install

any ideas?

thank you!
