Ulises,

A lot of online hosting is shared-hosting. Shared-hosting is the cheapest way to start your website, but it is what it says it is: shared space. Your site(s) are running on the same server and using the same resources of select other sites that might be provided by your host.

Due to the stress of operating multiple different websites of different functionality and purpose usually leads hosting companies to push limits on customer's websites. PHP Executions can be one of them. If I recall correctly, each call to a PHP function executes it to run whatever logic is in the script. This is limited so a shared server won't be overrun and everyone gets their share. However, this can also be pushed onto VPS online hosting as well, check with your provider.

All in all, I recommend checking out the article Dave shared, and to consider upgrading your hosting plan (from shared to VPS if you're on shared hosting) to one with more or unlimited memory usage. Especially if you're going to be running 4 different Oxwall installs on the same plan.

Thanks,
