Thread:Talk:MediaWiki/The file you submitted was empty error in MsUpload extension/reply (2)

I have multiple MediaWiki instances hosted on a single server. Users reported that they were getting file upload error "The file you submitted was empty" for few instances. When I checked Apache error log, found the error " “write failed: No space left on device”. So finally the issue was due to lack of space on server. Once ample space was created, the file upload error was automatically resolved.
