“More acks than expected”, connection closed

i am using Smack 4.0.3

Every once in a while I get a message on the server from the client that looks something like this:

INCOMING MESSAGE!!!!!!!!!!!!
<message id='2u650-31' to='xxxxxxxxxxx@gcm.googleapis.com/Smack0152E3A3' type='error'><error type="cancel"><not-acceptable xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/><text xml:lang="en" xmlns="urn:ietf:params:xml:ns:xmpp-stanzas">Received more acks than expected.</text></error><gcm xmlns="google:mobile:data">{&quot;to&quot;:&quot;ClientsRegistrationIDGoesHere&quot;,&quot;message_id&quot;:&quot;1054919404&quot;,&quot;message_type&quot;:&quot;ack&quot;}</gcm></message>

After this error I get a stack trace that looks like this:

The error that pops doesn't seem to effect anything else, everything keeps sending and coming in as it should but after this error start popping, it will continue every 5 seconds.

Question How do I catch this error? The error only appears in the xml.  Better yet how do I prevent it?

Any ideas?
