Why my proftpd sometimes can't login?
I have install linux 9, proftpd 1.29,linux 4.0 on my server.
The user information are stored in mysql.
And I am sure it work, but sometimes my user says it can't login in for password incorrect.
I also have some try, and found that it has about 10% possiabliity wan't work!
BTW:I have configure 3 viture domain.
Any one can explain it?
