Logos: Why is the Indexer being run when L4 starts

OK, this has been happening for a while, but could you please explain why it is happening. Are these instances below due to an error somewhere?

What does the Indexer log say for each of those cases?

The third came from http://community.logos.com/forums/p/10933/85810.aspx which attracted my curiosity.

#1 is the first startup of B7, then I closed it and produced #2.
