Re: 100% cpu with double slash in beginning of URI (Linux64)

This means that your httpd process is stuck waiting for file descriptor number 7. 

You should now look at what this file descriptor is. "lsof" command is useful here: "lsof -p PID" where PID is the PID number of the stuck process. In the fourth column look for number 7 followed by either r, w or u (or maybe some other character). This is the file descriptor that is blocking your process.

And it blocks (for several minutes at least) while the cpu is 100%.
