Hi folks, just to clarify...
We don't need anyone to clear out any large images or PMs or anything of that sort. Nothing like that hurts our server (and in fact, we want to encourage members to share whatever they'd like with one another that helps them).
But super long threads made up of thousands of replies can tax the server a little. Usually that's not a problem, but when a search engine is indexing those threads in the rapid manner they often do, it can spike our loads to where everything comes to a crawl. So the easy solution is just to keep such threads limited to under 100 pages in the future...
Everything else you can continue doing as usual. It's no single member's behavior or anything of that sort that is causing our recent issues. It's just a combination of a whole bunch of little things that seem to be happening, so we're just trying to do what we can in the short-term to keep everything up and running until we move over to the new server. And to not press our luck with the new server, we're likely to keep the 100-page thread limitation in place.
Thanks again for your patience and understanding,

John
