When last I looked into this, with a user, we found that it's related to some libc change; see:

  https://github.com/proftpd/proftpd/issues/1134

The "fixes" are to either a) use a SQL database (even SQLite) instead of the plaintext AuthUserFile, or b) manually change the ProFTPD config.h settings (as discussed in the above ticket).

I'm not sure why the buffer sizes in libc, for these functions, was changed.

Hope this helps,
TJ
