(Seemingly) random session destruction

[eluser]treeface[/eluser]
Hello all,

I'm curious if you could lead me in the right direction as I'm a bit confounded by a problem I'm having. Every once in a while as I'm browsing my site, I will be logged out. The only pattern I've been able to find (and I'm not sure this is even accurate) is that it tends to happen more often (though not always) when I make a second get request before the first one has finished. Basically what I mean is I will click two separate links in rapid succession before the first click has had a chance to complete its task. It doesn't always destroy the session when I do this, but sometimes it does.

If anyone has any ideas, I'd love to hear them...

Thanks!

<b>edit:</b> I've been able to track down the exact process by which I can replicate this now. If you click one link, wait a half second, then click another *before* the first link loads, it destroys the session. So there's a period of time after the first GET has processed (I assume) the session class and before it's executed its operation where it will log me out if I click another link.

I'm at a complete loss for where to start with solving this. Thoughts?
