How did you ascertain the fact that the overlap is good ? (I presume you
checked the transform, but I don' tsee it printed in the log). There must be
a significant drift in teh transform from teh initial position to the
position after 174 iterations to prompt this error.

DId you try resampling with the transform and overlaying the images to make
sure that the transforms are headed in the right direction ?

1/10th for MI is plenty.
