mesh quality not achieved

I am trying to simulate a problem where the particle is moving in the domain. So i have used moving mesh (ale) and assigned a value to prescribe mesh velocity for the particle's boundary. The particle has been considered as moving wall and it moves at the same velocity as the mesh. I have also decreased the minimal mesh quality to 0.001, but still it is giving the error " Requested mesh quality could not be achieved".

Can someone suggest to fix this error ??
