JT suggests a solution might be to insert a small 750 ms delay after each fep_xfer. This lets the ATMS server catch up and allows the client to refresh. Downside is may extend the time to send the entire highway model to the ATMS past the 30 second interval.

JD suggests a solution might be to send all stations on the line during each fep_xfer, thus reducing the total number of xfer's required. Downside: may get "can't encode arguments" error is the message exceeds RPC limits.

  • Priority changed from Urgent to Medium
  • Severity changed from Minor to Major

Current workaround is to send just the "triangle" info, a subset of the entire region. This improves the client UI responsiveness. So I'm reducing the priority of this issue.
