Pardiso behaviour having right hand side "B" all zero.

[Omer_Riaz]

I am using PARDISO solver for my code. I am having problem if my right hand side is all zero. For all zero B the solver stuck in solution phase for inifite time and niether it exit from solution phase nor it gives error. Does PARDISO works with all zero B? Is this known problem in PARDISO or do I have to set some parameters to aviod this?

Thank you

This is a guess, since there is nothing specific to explore:

Pardiso allows iterative refinement, and this can be a problem in the special case where the solution is a vector of zeroes.

Please show a short example of the problem.

yes, short example would be very nice to have.
