#1 turned out to be invalid, my logging was simply bad (I was logging the number of messages I'd read so far for that partition, not the requested read offset)
#2 is still valid, though. I'm thinking that a possible explanation might be that the part of the log I was processing was deleted, but I'm not sure yet.
