Will your work on the system do something to improve load times and the on going, never ending,dad-ratted 404 Page Not Found error messages that pop up when opening forums or threads with in those sorums.

Somedays I try to open a forum or thread and nothing happens for several minutes and then I get the error message. Some threads don't open and I don't get an error message, they just don't open. When that happens, I may be able to open other threads. Often, I have to leave THR, surf another forum or two and come back. I may be able to open stuff then, but it is a crap shoot if anything is going to work.

I haven't seen the problem myself, and haven't heard any complaints.

How often are you seeing that behavior? Is it at particular times of day? What ISP are you using? How long has it been going on?

It's you Jim, everything seems fine from my end.

Well, it could be on my end but I don't have any problem with other boards running vB. My ISP is MSN/IE, it doesn't matter what time of day it is. Yesterday I had the problem both in the morning and around this time in the afternoon. Sometimes when I try to get in here, I get the "THE HIGHROADORG logo and part of the buttons at the top of the "page" and then everything just sits there and sits there and sits there. I go to another vB web site and everything pops open with no problems. I've had the page not found error messages with this site since it officially opened.

The other day I opened a thread that was shown to be two pages long, all that opened was the first post. I could not get beyond that point.

Like, I said I don't have any problems getting into other vB web sites.

Hrmmm. Odd.

Next time it happens, delete your internet cache (including offline files or whatever the prompt says) and immediately try to reconnect. See what you get.

If it still screws up, post here again.

In the mean-time, I'll try and get snmp running in-house so I can keep constant tabs on bandwidth. The server is so underutilized it's funny, and we're getting about one "slow query" in 1,000 (multiple queries are sent per page) so I don't think it's an issue with responsiveness of either the web server or SQL database.

The yellow line is the important one -- the visual tool stacks 3 measures on top of one another, but for the most part we're seeing about 0.4 threads waiting to be processed at any moment on this particular dual-processor box (2 is optimal ;) )

Note that we've seen 96 simultaneous SQL processes in the past and everything's been nice and happy. Haven't see that much lately, though.

Now, we did run into problems a while back with running out of Apache threads, and we haven't recompiled the software yet as the problem went away (I think someone got bored). Hrmmm. Maybe the changes we made to react to that are affecting you. You're on dial-up, right? It may be that after a few seconds of not hearing from you it's timing out and you're seeing issues because of that. Hold on and I'll toggle a setting -- we'll see if that makes it go away.

Play with it for a day or so and report back with whether you're still seeing the problem.

We had the keepalive timeout set to 4 seconds -- if you were having a slow time connecting (like your mail client monopolized the connection for a few seconds) that could have caused the connection to break. It's at 10 seconds now, which I believe was the original default.

Let me know either way.
