Normal, and harmless.

This means that more than one process is syncing the same collection  
at the same time. So the current process dies, letting the first  
process complete. This can sometimes occur when you explicitly trigger  
a sync on the device while it is already PINGing.

This means that, for whatever reason, the device did not receive  
and/or understand the response to it's last request, so it is  
repeating the request. We count the number of times this happens to  
prevent infinite sync loops.

This means that the current syncState has been removed, as would  
happen when you remove the device from Horde (or manually from the DB).

This is similar error to the above error that occurs when the state is  
removed during a running PING.

Without more information, it's impossible to tell what is wrong. The  
error messages above can all be attributed to normal/expected behavior.
