Error in sparsesolver or UMFPACK

Hello, I am trying to solve a system of poroelasticity using P2 elements and sparsesolver. Number of mesh elements - 43936, number of mesh nodes- 21974.

The output I am getting is :
Error umpfack umfpack_di_numeric status -1
Error umfpack_di_solve status -3

I would like to ask what does this message implies.
