[RegCNET] problem in running RegCM4

[pyarimohan maharana]

Dear all,
i am using intel compiler (10.1.011) for running RegCM4. i was able to
simulate for few years. but recently when i am running RegCM4.0, it is
showing CFL violation and suggests to decrease DT.
i decreased the DT to smaller values  but the same problem is coming again
and again.
