I think this is not an error. Try start a MD simulation from that point. In my 
system it works fine.

Have a look in the end of my log file of the minimization step: 

Steepest Descents converged to machine precision in 36 steps,
but did not reach the requested Fmax < 1000.
Potential Energy  = -7.5158275e+05
Maximum force     =  1.8681875e+03 on atom 1
Norm of force     =  2.1719547e+05
No MEGA Flopsen this time
