  • [Forum] Server Load and Database Errors - 4.1.10

    Hello everyone,

    I am running a 4.1.10 vbulletin forum. We have about 2,000 members of which about 1,000 are active every day. Our database is fairly large at just under 1gb. We started off the forum on Rochen hosting, but grew too large for their shared plans and didn't want to break the bank on a VPS solution with them. We ended up moving to Liquid Web. We have had a generally crappy experience with them. Our bandwidth, while mostly normal with Rochen, almost tripled in our first month with Liquid Web. This caused us to have to upgrade to their high end shared hosting service. That ended up not being enough and we upgraded once again to a VPS. I thought this would solve our problems, but it has not.

    We recently upgrade to 4.1.10 and have had many issues ever since. Our server load, as monitored on the Liquid Web dashboard, jumps to extremely high levels (15+) about once every other day. This causes the server to lock up and throws out database errors to users. We've had discussions with LW support, and they have always pinpointed several issues. Number of client connections being high, memory limits being too low, and various .php functions using lots of resources(showthread and forumdisplay off the top of my head.) We had them increase our client connections and decrease our memory limit, but this didn't help things much.

    Is there anything I can do on my end to help the issue out? I'm not the most knowledgable admin, but it doesn't seem like there is much I can do to fix this and it seems like it is on their end. If I can provide any logs, or error messages to help diagnose the problem, please let me know.
