I run BOINC V7.6.33 as a service under Windows 10. I shutdown the PC each night.
For the past few nights all running MIP work units error during PC shutdown. Earlier results have already been removed from Results Status. The following logs show the errors occur on shutdown and not startup.
Has anyone else noticed this? The errors are not noticed by Boinctasks as I think it has already been closed before the errors occur.
