I suppose this is due to the write-ahead logging nature. Workaround: truncate files to be deleted to make room for the logs. Suggestion: consider implicitly truncating a file to be deleted if there is not sufficient disk space to delete the file otherwise. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
