 Dear all,
 I want to optimize a structure which contains Ru (charge 2 and multiplicity
 3)by ump2/dgdzvp  and because of the following error I cannot do it.
 ===================================================
 Error on total polarization charges =  0.01799

 Do you have any suggestion to overcome this problem?
 Thanks in advance
