Jobs on our Windows slave machine are often failing with an "Unable to delete directory" error. The directory isn't locked, etc. and a subsequent run may succeed. This happens with various jobs and with different directories. It just started occurring within the last week. No backups are running during the build. We have tried updating Jenkins and the P4 plug-in, as well as Perforce on the slave machine to no avail. Any suggestions or workarounds would be appreciated.
