Exception Caught

What these exception caught messages mean? I think it has something to do with the network navigator, but wondering what it complains about network navigator/networknode? I appreciate if you could tell me what you can see/read the problem or a clue from the message.

You can also turn on the Event Log and see what event happened right before something went wrong.

If you have an exception in your code, there will be a line in the event log showing that exception. The event immediately above the exception line is the code that threw the exception.


That output is a stack trace:
The exception was thrown in NetworkNavigator::querydistanceextended, which was called by NetworkNavigator::navigateto which was called by TaskExecuter::begintask, etc.
