Fatal error: Allowed memory size of 805306368 bytes exhausted!

Maybe, and maybe not. It depends on what function(s) you’re trying to use at the time. Things like a couple of DB calls and outputing some HTML shouldn’t take that much memory, but processing large image files can take that much memory easily.

So that’s the big question – Where do you get this error message showing up? What are you trying to do at the time?

The error shows up in the user directory page so there are quite a few images. I have about 7200 members but the memory only requires the users shown per page right? I doubt the 20 I show per page takes up that much memory.

Unless it’s doing some image processing in the background, that does seem like way to much memory to be using for something like that.

What theme/plugin is producing the user directory pages? It seems like there’s either a problem with how it’s doing that, or there’s some strage processing going on that’s taking more resources than it should be.

I’m using a plugin called userpro that is kind of like an alternative to buddypress. The member directory is the page that calls up the users. I actually cloned the website to my local pc so see more in detail what was going on. MySQL reported about 2400 selects per second when I brought up the page. When I bring up the user page in wp-admin it peaks at 300 selects per second. They are essentially doing the same thing. But I’m a bit confused because my database is 83mb.. the entire website together is 2gigs. My web host (linux centros 6) has 4 gigs of ram. I’m not exactly an expert on how memory is handled but it seems like it should be enough to cover the website.

It should be, and that’s why I think that the plugin is doing something strange.

As it’s a commercial plugin, you should go back to the author/vendor and ask them for support. No one here has access to the code of commercial plugins like that so we can’t see how they work, and if there is a problem like this, the author really should know about it so that they can fix their own code instread of letting the errors live on.
