This plugin has caused my entire server to crash. I have a website that has about 10,000 pages and about 5,000 daily uniques. I have been running this plugin fine on wordpress 2.9.2. After the upgrade to 3.0.1 I did not change any settings or add any new plugins... I get an email from my hosting company saying that my site is using alot of resources do to the fact that my apache process are hanging? I had no clue as to why this was happening so my servers technician deiced to take a look at my blog and he narrowed it down to this plugin. Once he shuts it off and reboots my server everything goes back to normal but as soon as he turns it back on and traffic starts coming to my site the plugin starts causing apache process to hand and it eventual builds up to the point were my server is non operational. I have tried this on a shared server and a dedicated server and It still happens.
I don't know if this plugin was made for a blog site as big as mine? if anyone can share some insight I would greatly appreciate it.
