Contraindications

Problem description

Whenever vsftpd opens a local file for transfer, either GET or PUT, it does so specifying the O_NONBLOCK flag. In an XFS DMAPI filesystem, specifying O_NONBLOCK for a regular file means that the application wants to be notified if the file's data is not immediately available. The kernel will return EAGAIN in this situation, and that's what causes vsftp to think that the transfer has failed.
Also an issue is fixed that caused vsftpd to become unresponsive when run under heavy load and lots of connections.
Issue fixed: vsftpd logs wrong time stamps before version 2.0.4
