Sorry guys, I was getting the run around from the site's webhost for about 3 days before I really got an answer on how to fix the problem.
The issue basically is that the forum's membership is too big for the webhost's servers to handle. The issue of the "max user connections" is based on how many times people connect to the board. While the board can handle 100 people on the site at once, basically if 50 or more of them are looking at 50 different pages at a given time, then it overloads the board since my host's server only allows 50 connections.
So basically, I cannot guarantee it won't happen again. I believe my current contract with my webhost runs out in August, so between now and then I will look at different webhosts in the event that this problem doesn't go away (I don't think it will) that will allow more than 50 connections.
The solution my webhost offered was to go from a shared server (which the site currently uses) to a virtual private server. The only problem that incurs an additional $400 annual cost, something I simply can't afford right now and even if I could, I don't know if fixing this problem is worth it.
But I'm going to see if I can increase the site's ad revenues in the coming months to potentially pay for that.
The board is up for now, but this problem could come right back. It could be 12 hours, 12 days, or 12 months before this problem crops up again, but I'm pretty sure with my current hosting plan, that it will crop up again. I just don't know when. I'm hopeful it doesn't happen between now and August in order for me to find a more permanent fix.
Thanks for the info, Pudge. Youand I might need to start weeding out some of the "less desireable" members to ease the burden, perhaps. Float me Admin privileges for a day or so and I'll tweak the database for you if you'd like. You're welcome.
[OK seriously, good job getting things back up. Why not set up a paypal contribution link? I'm sure many of us would be glad to drop a couple of bucks occasionally to help the site out. You could even show a running tally vs. target if you ar concerned about getting "too much" contributions.]
