Out of curiosity, one of my WUs experienced an error: http://www.primegrid.com/result.php?resultid=770889898

It seems that the CPU took roughly about 1/3 of the time it normally would. What's strange is that this is an isolated incident, it happened 1:900 tasks. Its also running on a Xeon E3 with ECC Memory so I don't know what could have happened.
Could someone take a look at the WU, if other than curiosity?
