vsftpd issue with large style.css file using FTPS

[ken]

Users are unable to modify or download files named style.css in any given directory and in multiple clients. FileZilla gives a GUN TLS -15 error. It can modify any other file without issue. If I rename it to style.css~ for example it works fine.

This only happens with TLS enforced.

Any ideas? I have no clue what's causing this at this point.

Disabling ascii downloads fixed the problem.
