I did some checking and the error rate for Windows 8.1 (and Windows in general) is well within the normal range. There also isn't a particular user that accounts for an abnormally high percentage of the errors. Keep in mind, that although the actual error rate is low, a higher percentage of your work units are going to be resends when your host is a reliable host.

If the system works to spec, they'd all see 'This computer has finished a daily quota of 1 tasks?', i.e. 1 task allowed in 24 hours, and if failed, no more till tomorrow. The 65K USD question is, what's the success rate for that particular OS versionm, and is it this VINA science only? If 50%, then that's what it is, and the monster will continue to be fed, piece meal.

tonyh205,

That error is from SCC1 which is different than the original post, but I went ahead and checked for SCC1 also to be safe. For SCC1 with the OS name/version Microsoft Windows 8.1 Enterprise x64 Edition, (06.03.9600.00), the _real_ error rate is <1% (this excludes errors such as no response, unstarted late workuniit, etc that would also generate resends). For SCC1/Windows 8.1 in general the real error rate is also <1%. For SCC/all Windows in general the real error rate is <2%. The error message you posted above would fall into that real error rate.
