I would suppose your performance monitor will tell you if CP is storage 
constrained and guests are awaiting page frames.  DTCVSWx just sits there 
sleeping, waiting for a Sign.  If the OSA hiccups, DTCVSWx will awaken, 
trigger error recovery, then turn over and go back to sleep.

Is DTCVSWx showing signs of sluggishness that makes you suspect memory 
contention?  (He will probably be paged out due to inactivity.)
