javax.net.ssl.SSLException: Received fatal alert: bad_record_mac

I’'ve createed some xmpp extensions; and am send a high volume of them from my smack client to my plugin within Wildfire. At periodic intervals I receive an ssl exception; from within smack and am not 100% sure how to troubleshoot it. I cannot catch the error as it is not bubbled up so any suggestions\insite as to its cause would be appreciated.
