Problem: Eigenvalues close to 0/0

Hi, I met a problem in the deterministic model. When I check the steady state, there is error information of the eigenvalues as below:
??? Error using ==> print_info at 51
One of the eigenvalues is close to 0/0 (the absolute value of numerator and
denominator is smaller than 1e-6)
Error in ==> check at 51
print_info(info, options_.noprint);
Error in ==> begin at 129
check;
Error in ==> dynare at 120
evalin('base',fname) ;
I want to know how can I solve the eigenvalue zero problem. Thank you so much!
