Insufficient Memory Errors
In a previousblog, I discussed how to set up WordPress from a home-hosted computer, so that it could be edited from within the LAN.
1. For the desktop computers, editing the hosts file was necessary so that the theme being used on the blog could be visible from within the LAN.
2. Since iPads do not have a readily accessible hosts file, it is necessary to have them use a proxy server, and edit the hosts file of the proxy server.
The issue I had is with #2. I have several applications running on my Raspberry Pi: a driver for a DVB-T stick, mysql, nginx, php, and additionally squid acting as a proxy server so I could access the themed version of my blog from an iPad. The proxy server proved to be too much for the Pi, and php kept on crashing. I was getting insufficient memory errors. I run the quick cache plugin on WordPress, and this probably uses memory as well. I turned off the proxy server squid (which must be using up extra memory as well, to pre-cache web pages), and haven't been receiving the errors anymore.
For the time being I will be limited to seeing the themed version of my blog from my desktop computers. A possible solution, I think, would be to configure squid so that it uses less memory. Maybe a page file/swap space instead? More on this to follow later.
