Sent to CCL by: xunlei ding [dingxunlei###gmail.com] Dear CCLers, Sometimes the G03 jobs halt at L103 and the last two lines of the output file are " GradGradGradGradGradGradGradGradGradGradGradGradGradGradGradGradGradGrad" and "Berny optimization.". The jobs will not stop unless I kill them. Does anybody know how to solve this problem? Best regards, Ding
