At the start of every build TeamCity always logs the following:
[09:54:55]: Checking for changes
[09:54:58]: Clean build enabled: removing old files from E:\TeamCity\BuildAgent\Work\e44ad1e9ea263f29
[09:54:58]: Clearing temporary directory: E:\TeamCity\BuildAgent\Temp\buildTmp
[09:54:58]: Failed to delete empty directory: E:\TeamCity\BuildAgent\Temp\buildTmp
Can this problem be ignore or should it be investigated?
