Over the past few months I’ve been noticing that my virtual server (omicron) has been frequently using over 80% of it’s available memory. This is likely due to the fact I started hosting a ruby on rails application (redmine) which means another set of processes (mongrel cluster) running the whole time in addition to what’s already there.
For the record, omicron is currently running:
- Apache, mod_php, mod_python
- Tomcat behind Apache mod_proxy
- Mongrel cluster (load-balanced by Apache)
- Subversion via Apache mod_svn
- MySQL
- PostgreSQL
Over the various sites I’m now hosting omicron pushes around 80GB of data a month, most of it coming from a couple of wordpress blogs (this one included).
Before the upgrade this barely fitted in the available memory – although it was perfectly stable it would swap like crazy once under reasonable load. This, to me, means it’s time for some more memory.
So upgrade time it is. In fact, was – if you can read this post then omicron is back online – with twice as much memory (1GB) and twice as much disk space (40GB) as before.
Hooray for upgrades!
