Looking through ip__resolve_ams, I noticed the check for if (al.sym) and realized, most times I have an al.map definition but sometimes an al.sym is undefined. In the cases where al.sym is undefined, the loop keeps going even though a valid al.map exists. Modify this check to use the more reliable al.map. This fixed my bogus entries.
