      We migrated Two days ago.  
      I dumped the repo to a new physical machine and imported it through the Web Interface.
      Every day, at some point, the repository becomes inaccessible.
      I RDC to the box and Apache is using 100% of the CPU.  The entire machine is performing ridiculously slow.
      A restart of the Service restores CPU to normal and everyone carries on until the next occurrence.
      I parsed the error log for yesterday counting occurrences of all AH errors:

      I looked at the error log unto the point of the restart.  I could not see anything obvious.
      I also look in the event viewer and see nothing.
