AMR memory allocation failure during load balancing

Occasionally the mpi buffer for AMR load balancing exceeds the vram limit and leading to a segfault. This is a feature rather than a bug, but it would be nice if this can automatically trigger saving a rst file so that one can restart with more gpus at the point of failure
