Large rotations in CASSCF

Dear experts,
 I'm doing CASSCF calculations using G94 and getting  several warning messages
 of this type:
  WARNING! : large rotation  I  J  =          110           5
  Step scaled by    7.0061957246605036E-02
 Often the job ends up not being converged.
 What does the warning message mean? Is there a way around to overcome this
 Thank you very much
