I've attached some charts from Zabbix from the last 12hrs. It looks like for some reason, it climbs up to use all the RAM, then every few hours releases 100-250Mb of RAM, then slowly eats it back up. I've tried looking around in top etc to try and track down what's gobbling and subsequently releasing memory, but haven't had that much luck.
Are there any better tools for tracking down memory use, or any scripts you have that you can post here to help me pin this down? It's really not that critical, I'm just trying to understand why it's fluctuating so much, and make sure I don't have something floundering.
P.S. I know the SQL processes were climbing; I think that was based on some key buffers & query caching changes I made last night. Didn't appear to have any effect on the RAM usage in the same timeframe though. Part of what piqued my curiosity.
