oh yeah!!
Why did boinc make such a mistake and found a p_fpops of 30197620000000.000000? it's crazy!
what can i do to correct the problem on other hosts? reset project?

I can't test new tasks now because all my hosts goes offline this night for holidays but i come back after and check all new tasks in error.
Thank you very much for solving this mysterious problem!
Merry Christmas

I have some task with inconclusive results, all with computer 10377786 as wingman.
All task of this computer seems to get inconclusive results or error.
Some other computer like 10389447 or 10404779 also produce a lot of inconclusive results.

Hi All!

With lhc@home consolidation, did you consider to balancing credit between applications?
Actually, there is so much differences between projects credit calculation, and it's not fair to merge ranking in these conditions.

Hi!

There is a lot of WU to send now, and all my hosts receive a lot and get cache full :-)
But one of them not receive wu.It's a virtual machine under linux amd64 and xeon processor.
My others ohsts are physicals machines with intel i5 and linux adm64.

There is a problem with the intel Xeon and linux amd64? or with virtual machine?
Why only this host don't receive wu and can't get cache full?

Thanks!
