Pure-FTPD Login Fail

Hello,

i got a Linux CentOS 4.5 Machine Running Lastest cPanel release with pure-ftpd

but is run for 6 hours OK then is get login fail for all FTP users,

i really tried to force cpanel update and i tried to reinstall Pure-FTPD and seems that still not working and Unstable

but I Switch with ProFTPD is working for a 2 weeks Stable without any troubles but i believe that Pure-FTPD is Light FTP Daemon and also is more secure and fast

so i really need to switch back to Pure-FTPD again but i need it to be Stable,

anybody had faced a kind of this problem ? or know what shall i do through it ?

 

I'm still facing this problem, can any one help ?
