My site seems to be falling a part the last few days (slowing down / freezing).

I have plenty problems in my error logs. Been told by drmike that I have memory limit problems, most of the errors point to my db.php though and referrers which are from the affiliate plugin...

Here are some logs:

Would this be memory or something else?

Thanks!
