Wow. What a weekend. Decided to upgrade MySQL to allow the upgrades of a couple of other things on the server, and it was a "downhill" event. Everything looked good when I went to bed last night at about 1am. But then when I woke up this morning, Apache was down.
Too long of a story to post, but let us just say that there are many things now upgraded and all once again working in harmony.
