What kind of entropy source did you select? EGD or the integrated
entropy collector? (If you did not select one, the integrated collector
should be configured)

EGD can be drained and then an upstarting sshd can fail. I have written
my own prngd to come around this problem (early alpha stage :-) on HP-UX.
The integrated entropy collector should better not fail...
