I'm currently running WordPress 3.5.1 for the last 2 months on dreamhost using VPS. When the site launched, every few days it would run out of memory and need to be rebooted via the control panel.
I investigated the code for memory leaks and memory usage carefully and implemented caching. This made the site run for a week at a time before needing a reboot. So it helped but didn't solve the issue.
I cannot continue to reboot the server weekly to keep it running. Anyone have any suggestions on how to track down what's causing this?
Here's some data that may help.
Currently allocated memory: 600 MB
WordPress version: 3.5.1
Plugins: Askimet - Advanced Custom Fields - Hierarchical Link Categories - WordPress Importer - WP Memory Usage - WP Super Cache
