Ended up being a complicated little mess. Problem was the database server would stop answering network connections, causing all the web clients to get stuck. It took awhile to figure out why. It turns out that the DB was configured to do DNS lookups on client connect. Because the DNS service is running on a very busy machine, random DNS queries were getting dropped. Apparently there’s some kind of bug in the DB that wouldn’t timeout a connection if it didn’t get a DNS response, so eventually the whole system gummed up and stopped responding. 0 activity, no system load, and just zilch.

Only showed up when the site was very busy. I disabled DNS lookups on the DB and it seems to be okay now. We’ll see how it goes.

Now that's exactly what I've been trying to say, but don't have enough knowledge in technical terms to explain myself.

Just so you know...we appreciate everything you and Jim do to keep this sanctuary from the madness up and running.

It’s got to make you want to pull your hair out sometimes, though! LOL!

Sounds complicated to me but I am always in the center of denial. Lov you still. You must have a very stressful job.

Is this the problem that's been slowing FR down during high-traffic times for the last several months? In other words, do you think you've found THE problem?

Thank you for all of your work, I’m sure it can be quite frustrating. We appreciate it very much, as we’re all a bit addicted to FR ; ) Blessings to you.

Yep..and that's what I got on this end when Windows sought a solution. Said your system was not set up to connect with my computer.

Hey John,

How come all times are in PST now and I can not set them for my time zone. That option longer appears in my preferences.

Thanks.
