I migrated from TFS 2015 to TFS 2017 and after the upgrade I moved the distribution of the artifacts from the build to a release-step (after the build-step).
In the release-step I delete all content of the output-folder (on a network share) and copy the artifacts and some needed setups (laying on a network share) to the output folder. Most of the time the copy process works fine but once a while (once every 4-5 tries) the copying of the needed setups fails with a bad-file-descriptor:

I'm thankful for every hint, as I don't have any idea where to start...
