In order to formally reason about distributed Erlang systems, it is necessary to have a formal semantics. In a previous paper we have proposed such a semantics for distributed Erlang. However, recent work with a model checker for Erlang revealed that the previous attempt wasnot good enough. In this paper we present a more accurate semantics for distributed Erlang. The more accurate semantics includes several modifications and additions to the semantics for distributed Erlang proposed by Claessen and Svensson in 2005, which in turn is an extension to Fredlund's formal single-node semantics for Erlang. Themost distinct addition to the previous semantics is the possibility to correctly model disconnected nodes.>>> af++
