vsftpd на дерзкой человечности - “OOPS: Ребенок умер”

There was a bug in vsftpd that affected 64-bit machines, here's the bug report - it looks fixed on Red Hat's distributions but it's not yet fixed on some other distributions.

As a workaround, you may add seccomp_sandbox=NO to its configuration file but that will disable a sandboxing feature (not sure about what it does exactly, but if security is your priority you shouldn't use FTP anyway).

echo "seccomp_sandbox=NO" >> /etc/vsftpd.conf
