On the snapvault secondary, can you enter the following command?
'snapvault modify -t 2 /vol/vol_name/qtree_name'
For example, if the snapvault secondary path that has the lag of 5 hours and receiving the transfer error is being replicated to /vol/vol1/qtree, the command would be
'snapvault modify -t 2 /vol/vol1/qtree'
