Error

I find this interesting. I added 1 new agent today, and decided to check.
When I selected the error log, all of these other agents appeared as well
(Backstop was my new one to add).
What I find interesting is that I check this log fairly regularly and edit
each and every one until the error log is empty. So what happens that
makes entries that were valid become an error?
I’m assuming the agent is removed from the locator when the ‘error’ occurs,
and go back into search results once the error is fixed?
