Database Software

The repliction scheme: master—“timesten1” and subscriber—“timesten2”.
I set the the connection attribute of PermSize to 2G on both machines.
Howerver, during the testing, the issue comes up on 'timesten2':

Well , the insert operation succeeded on 'timesten1', and the permanent space allocated is same, why the insert operation is failed on 'timesten2' ?
