I am constantly struggling with large amounts of cached memory on my VPS. Rebooting only helps briefly and then it tends to shoot back up to over 400 MB. That is way too much for my site still being in the developmental stage.
And it was not always this way. It use to stay below 300 when I was running both Drupal and Wikipedia. Last week, I took down the Drupal site, and it still was hitting the 512 MB edge.
Is there any way to clear the memory cache or to limit it in size? And can anyone give me good instructions to see just where the cached memory is going?
Thanks In Advance,
