 Hey there,
 This problem has been found by many people (including me). For a lone
 period of time, there seems no good solution to that. We actually
 believe it is caused by insufficient memory. Try increase that
 (significantly). Another thing you might wanna try is, not to use
 Gaussian. GAMESS and Q-Chem have much better algorithms and require less
 system resources.
 Good luck,
