Sync issue

Hi… I’ve got a pair of Macs on one network and I’m trying to use a direct connect sync using the beta sync plugin… I can get them to start the sync but after a few minutes of running over a WIFI connection I get the following messages :

It does this no matter how many times I try… I did look thru the console log debug messages and found this on the receiving side :

Any ideas? Does this mean that file is bad?

Could you start a Support Ticket to Development on this so our Sync team can have record of this? DEVONtechnologies Support Ticket System
Thanks.
