Re: With high request rate, server stops responding with load zero

Ok,  just to check it,  find out which file descriptor that your processes
is hanging on and then do an ls -l /proc/$PID/fd

Check a few of them and see if they are all hanging on the same
file.  Obviously replace the proper information for the variables listed
there.

Idealy something should be shown here to figure out what is the
problem.  If its reading from a file, check to make sure that the file is
still availble.  Network file systems can just wait on this forever.
