Archbot is the most stable bot ive used the 2 years of HB. Post full logg as an attachment since the important things is misssing.
next time please post a full log as an attachment, is impossible to see whats going on from just a small snipp it like the one you copied and pasted. what id suggest is installing Amplify, once amplify is configured and setup properly, you wont have that issue. you can grab it by clicking the link in my signature, and the install instructions are on the first post.
