Problem stsetch 2002-02-15 22:09:24: Loadlock gauge error

Loadlock gauge indicates high pressure.  
Pirani gauge seems flakey-  Sometimes 
it pumps just fine, sometimes it just stalls
at a high pressure and times out. 
When high pressure is indicated, system is stuck. 
Can't vent, can't unload.....
