Why do you think this is ChangeSkin related?

EDIT: As you can see in the log, the server checked the main thread (Server thread) for progress. However in this it shows some part of progress. This means a ticket took very long. Since it shows in all dumps a different code, it be caused, because the main thread starved. It got no processing/not enough, because there were too many other threads.
