I want to optimize geometry and to analyse frequencies for transition metals ($\ce{Cu}$, $\ce{Mn}$, etc.) compounds using GAMESS. I use Avogadro for preparing input files and I have a problem: one of my calculations terminates abnormally with the following message in the output file.

What is the actual problem and how can I overcome it?
