Strange numerical_error says "yPlusaMulx: y and x does not have the same length"

I have a strange error message on simulating my model in Comsol, as follows:

Error:
Time 1.339427726604487e-005:
Nonlinear solver did not converge.
Internal_numerical_error
yPlusaMulx: y and x does not have the same length.
Last time step is not converged.

It occurs only when I start to work on a remote desktop. If I don't do any remote desktop, the code runs very smoothly and is able to converge. My model is a 2D transient model.

Please suggest.

Thanks in advance,
Ashwini

Had the same problem with a stationary portion of a convective-diffusion problem. I think it's notation used in headers for iterative solvers. Might want to try GMRES or FGMRES.
