Sometimes, it fails in tst_QFtp::proxy or tst_QFtp::activeMode under the stress test. It complains about "Network operation timed out" on vsftpd.test-net.qt.local. When this issue happens in tst_QFtp::proxy, it shows "USER-ERR reject: 172.18.0.5 (ForkLimit 40)" in the log of ftp-proxy. By default, the ftp-proxy only supports 40 incoming client connections per minute. To make the ftp-proxy more powerful, this change extends the limits from 40 to 2000. When this issue happens in tst_QFtp:activeMode, vsftpd shows 426 Failure writing network stream error. It is a known issue of vsftpd. A quick fix is turning use_sendfile off.
