Two other options, depending on how much control you have over the server: 1) Use nginx instead of Apache (smaller memory footprint, leaving more for Python)
2) Use swap memory (http://www.cyberciti.biz/faq/linux-add-a-swap-file-howto/) ... not an option for shared hosting and certain types of VPS, but if you can do it and you're willing to put up with lower performance, this can be a good way to get your application to run without paying for more memory. I run development and low-traffic applications on micro AWS instances all the time by creating 1GB of swap. _Nik On 9/20/2013 3:18 PM, Mike Dewhirst wrote: > On 21/09/2013 3:34am, Carlos Villavicencio wrote: >> Hello, >> >> I have a django project running on digitalocean (in a 512M server) and >> suddenly it appears Error 500 on the Apache. >> >> I'm running wsgi and only 2 users (because we are starting) >> >> Looking on the logs, the errors were the following: >> >> 1.
