I didn't think they were, but I wanted to include everything I was
seeing in case it shed light on the problem I really was having.
Thank you for clarifying what the lines mean, though.

I understand, thank you! The question now becomes, what caused the
operation to time out? Could it still have something to do with the
server dropping an inactive connection, perhaps at the same time this
operations was attempted? If so, setting up a script to keep the
connection alive should still help, correct?

I appreciate the help!
