I would be inclined to try another version if I knew what the cause of this issue was exactly, and I saw in the release notes that the issue was resolved in 7.X. But I cannot just try a new version on a production server as an experiment. I've hosed this up enough thinking 6.2 was out long enough to not surprise me. I've not compared them on any server running multiple CPUs, but on a single physical CPU server I've yet to see 5.X or 6.X keep up with 4.X. I've been poo poo'd heartily for saying so, more than once. I would hope, and I do think, this is easily solved. I've already had one private email stating a binary upgrade to 6.3 solved the same problem for them. I wish I could find that email again 8^( DAve -- In 50 years, our descendants will look back on the early years of the internet, and much like we now look back on men with rockets on their back and feathers glued to their arms, marvel that we had the intelligence to wipe the drool from our chins.
