[Trilinos-Users] ilut: zero pivot encountered!

I am working on solving a linear system associated with my finite element code.  When I try to solve it, using an ILU preconditioner, I get the following error:

ilut: zero pivot encountered!

I have checked that the diagonal entries are nonzero. Can this error come up in other situations, such as if the matrix is singular?

Thank you,
