[FLASH-USERS] Strange error from Driver

Tomasz,

    My setup line is:

./setup SinkRotating -a -3d -site=draco -parfile="flash.par.1000M" +uhd

where I've modified the par file to make the cloud 1000M and extended the
refinement to 30 levels (along with the required changes to the sink
threshold density and accr radius).
