High CPU usage on a specific script after update to 4.0.11

Hi!

We are experiencing a very strange issue with a specific Wordpress installation in our Litespeed-based shared hosting server. After updating to 4.0.11 and with no other change whatsoever, when trying to open the WP index page, the lsphp5 process that handles the request hits 100% CPU usage and the page never displays. The error log gives me this:

2009-12-01 12:02:31.808 [INFO] [xxx.xxx.xxx.xxx.:2925-0#APVH_domain.gr:80] HttpEx
tConnector state: 8, request body sent: 0, response body size: 0, response body

and stracing the process gives me nothing! Any suggestions?

Likely a problem with PHP code, upgrade to 4.0.11 should not affect it. change in WP may cause it. You can try downgrade to 4.0.10 see if it helps.
