The server automatically generates a special spanning map (ERRORS) showing which nodes have compilation errors. Components can use this for general monitoring purposes. If the KeepMap option is being used on the server, this is also useful for spanning map importers to distinguish between current, and preserved profiles. Components can import the error map as follows:

  @map %subscribe: errors
  map ERRORS
  @errors count_$
  errors
  count_$ 0

In this case, the errors resource wil be a list of all the nodes containing compilation errors, with the =count_$_ field giving the error count for the corresponding node.
