errors

This morning, I was presented with quite the conundrum: one of my servers suddently started having about 4x the normal MySQL traffic it would have in a morning, and I had no indication as to why this was happening; traffic to the sites on the server was steady (no spikes), and I couldn't find any problems with any of the sites.

I recently had a problem with cron on one of my Drupal sites, related to an issue I'll be posting about soon (namely, using Drupal's built-in search with more than 4.5 million entries in the search_index table). When I manually tried running cron, I got a "Cron failed" status message. I checked the log, and it said "Attempting to re-run cron while it is already running."
