Thank you getting back, I will try Laplace.

Sounds like you're trying to fit a very complex model, which will take a long time due to the fact that adaptive quadrature is being used by -xtmelogit-. You may want to switch to the Laplace approximation to see if that speeds things up and then use adaptive quadrature only on the final model.
