Angier,
<= div>This is quite normal.  Heating a trapped fluid results in a = large pressure increase.
One day I had my hydr= aulics test stand near the hangar door. The sun came around and hit a pres= surized gear cylinder.  By the time I noticed, the pressure gauge was = on the stop at 2000+ psi.
I try to leave the= plane parked with the dump valve open.  I do however leave it cl= osed if there is a chance the plane might get moved while I am aw= ay.  You can still bleed down the pressure before walking off tho= ugh.
