Make staging server 32-bit
We have experienced lots of issues with our current staging server.
It has been decided that issues are related with the fact that it is mounted on a 64-bit processor instead of on a 32-bit one. The server threads are a lot more memory hungry on a 64-bit env than on a 32 bit one, and runs out of memory very often.
We'll need to move the staging site so a 32-bit environment.
The production env will not be affected by this change, except for the fact that some issues might get delayed until they can be tested on staging.
