When Kloxo 64bit became available, I installed it right away on two of my VPS hoping that it would perform better that the 32bit counter part.
After the installation, I encountered several problems:
- Webmail not accessible - (Horde or Roundcube)
- DNS server (bind or djbdns)
- Gets an error when adding new email addresses
- Could only access email using Outlook
I have searched the Kloxo website about thisbut it seems that the solutions are just trial & error. There is no definite answers.
Meanwhile, the 32bit Kloxo powered VPS has been running for more than a year now without any issues.
I am not really sure if the 64bit version of Kloxo got a problem or Centos 64 bit itself. All I know is that my 64bit Kloxo VPS is a pain to maintain.
Until somebody finds a solution to these Kloxo 64bit issues, I would be using the 32bit version.
