Replication connected, but not syncing. (no replies)

I've setup a two servers. SQl1 has the master database, Sql2 is supposed to be mirroring Sql1. Slave has been stuck at the same GTID for days. Any ideas?

#Slace on Sql2#
#mysql -V
mysql Ver 14.14 Distrib 5.6.21, for Linux (x86_64) using EditLine wrapper

#mysql -e "show slave status\G"
