CCL: G09: ONIOM error: Maximum number of microiterations cycles exceeded!



 Sent to CCL by: "Yelu  Shi" [yshi4---stevens.edu]
 I would like to perform an ONIOM (QM/MM)optimization with electronic embedding.
 I finished an ONIOM (QM/MM) optimization without electronic embedding first.
 Then with the optimized sturcture, I performed the ONIOM optimization with
 electronic embedding. When the optimization ran the first step, there was an
 error message: Maximum number of microiterations cycles exceeded! And the job
 was terminated. My route section is: # opt=maxcycles=512
 oniom(mpwvwn/gen:amber=hardfirst)=embedcharge nosymm
 geom=connectivity scf=(fermi,xqc)
 How can I fix this error and let the optimization running?
 Thanks a lot.
