Your screenshot doesn’t show any crash. It does show a WARN from the binding, that it had an error and is going to retry the transfer. This would be pretty routine stuff in itself for Modbus.
This sounds like problems looked at in this long thread, essentially if you have a “routine” serial comms error, the recovery may go wrong.
Some work has been done, so you might want to move up to Milestone or Snapshot version to get that, or wait for 3.1 release due soon.
