[求助] 求助：Turbomole 中 ired 步骤出现 Warning!

(1) 用turbomole优化一个两层的大分子，基态，一直不收敛。failed 信息为OPTIMIZATION DID NOT CONVERGE WITHIN 21 CYCLES
Restarting it after checking the gradient norms
might be a good idea... (grep cycle gradient)
用的方法是B3LYP/pbe0/tpss/b97d(都试过)/  基组SV(P)/tzvp/, $scfconv (6,7,  8,9都试过)
grid m3 or m4（都试过）

请高手指点啊!

（2）在define 时，ired 步骤总是出现warning，不知道这是什么的原因，与收敛失败有什么关联没有？以下是warning 内容：
