Getting error when using bicgstab

Hi cfd colleagues,
I'm using bicgstab method with ILU preconditioning to solve my linear systems on my CVFEM code.
When I solved the lid driven cavity flow the code worked fine, but now that I'm solving an inflow outflow problem I'm getting this error:
??? Error using ==> ilu
There is a pivot equal to zero. Consider decreasing the drop tolerance or
consider using the 'udiag' option.
I dropped the tolerance like MATLAB suggested without success...
Any idea about this issue???
Thanks in advance.....
