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. b.
