Mulltiple Insert into Federated Table Select From local Table

I have 2 sites, and there is the same database and tables at each site.
I use event to call the procedure that will insert into federated table select from local table from one site, but there is only this error message "ERROR 1296 (HY000): Got error 10000 'Error on remote system: 2006: MySQL server has gone away' from FEDERATED"
And I ran the procedure in cmd, there is also this message for this procedure, but sometime there is error message and the data seem ok to inserted into foreign tables.
What can I do for this case?
