The outside entrance loadlock door was intermittently failing to close.  Elmer increased the air pressure to the solenoid and put vacuum grease on the oring to help seal.  I think Mike checked the loadlock pump too.  Cesar found an air leak on the solenoid and a leak on the air line to the solenoid manifold.  He reset the solenoids and tightend the fitting on the air line.  This may need to be replaced as a little air can still be felt.  Wafers are cycling now and so far, no problem.
