We recently had a user who reported that his Lync Phone (Polycom CX600) was signed out when he came in first thing in the morning and it was sitting at a sign-in error page. The phone then was having problems signing in. We had to factory reset the phone is order for it to get reconnected.
After the user complained once again about a week later that he found he phone signed out, I had the local tech take a look at the phone. She tells me it was then signed in. Now i'm baffled. The phone was signed out earlier but then decided to sign itself back in and was working just fine. One thing else to note, we replaced the phone with a brand new one and still had the same issues.
I checked the DBAnalyze logs with snooper and found several errors that concerned me. Here is one of the errors I found:

The part that concerns me is the "ABNORMAL SIGNOUT" message. I found that this is happening to quite a few users around the company and quite frequently. Has anyone else seen this issue before and if so, any clue as to what an abnormal signout is? Upper-management would like an explanation and i'm not quite sure how to explain it.
Any thoughts?
