I am using Wordpress MU 2.7.1 and BuddyPress 1.0 and all over my error logs is:
Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.
So i traced the error to my access log and I found that these errors are being caused by some site requesting a file that no longer exists. Which should create 404 (not found) error, but instead it is redirecting the site to look somewhere else and then that place is telling it to look in the first place, causing an internal redirect which only stops once it reaches the maximum of 10 internal redirects. At this point it puts out a 500 internal error and when there are enough of them tends to hang my PHP and give me whitescreens on any page that isn't cached. Only rebooted php and my server solves the problem until google or someone else searches for a file on my site that isn't there, and brings my site to a screeching halt, usually about once or twice a day.
GET /wp-content/mu-plugins/bp-core/images/mystery-man.jpg HTTP/1.1" 500 612 "-" "Googlebot-Image/1.0
(BuddyPress moved from mu-plugins into plugins)
I have been told to check my .htaccess file, but I don't see anything wrong with it:
<FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$">
