Hello everyone, I gave Brian the url so that he can subscribe to this list but am going to post his email here. Could someone shed any light on the logs that he sent me and if there is reason to be concerned? I do not have enough experience to give him a qualified answer and am deferring to the advice of the experts on the list. Thanks in advance!
