Forum Stability

For a while now, I've had my forum constantly getting "Internet Server Error"s
I do not know what causes it exactly. There is no pattern to recognize when it's happening.
Months ago, I decided to get more memory on my VPS to fix this issue. I started with 1.5 GB of RAM and moved up to 4.5 GB of memory. This was no longer an issue.

However, I shouldn't have to be using 4.5 GB of memory to run just vBulletin, let alone 1.5 GB. There is another issue but I just don't know what.

How can I find out what the issue is?

Well, you're not getting "Internet Server Errors", but "Internal Server Erorrs", and you need to look into your server's error logs to find out what's causing them. If you don't know where to find them, ask your host.
