Comment 7 for bug 302798

Okay, I just realized that I used "running out of memory" with two opposite meanings. The master database is running without needing to fetch data from disk. I thought the app servers might be going into swap, but they aren't.

But things may be different on the slave database. The memory graph looks peaceful and constant, but most memory usage is filesystem cache. The daily staging updates may be washing slave data out of the FS cache.
