I have a production server with 16GB of RAM that came with a 32bit CentOs installation.
The website hosted on this server is increasing its traffic every day and I am having some MySQL trouble so I tried to check the MySQL configuration with mysqltuner.pl and gave me the following messages:
[!!] Switch to 64-bit OS - MySQL cannot currently use all of your RAM *** MySQL's maximum memory usage is dangerously high *** *** Add RAM before increasing MySQL buffer variables ***
So my question is: can I survive with the 32 bit? Or I will have to install the 64 bit OS?
