FPGA is not working with increased stp size

We are using 3 fpga 530 stratix IV.Let name these fpga as SP1, SP2 and SP3. We are sending data from SP1 to sp2 through lvds interface, where each channel is operating at the data rate of 1589.2gsps. 

Here SP1 data in the STP is coming correctly, in every case, and resource usage of sp1 is 35 percent. 

In sp2 STP data is coming correctly from SP1 when the input stp size is 1K and output STP instance size is 512K. Here SP2 resource utilization is 87 percent. 

But, when I increased the size of STP in SP2 all lvds channels start continuously toggling. 

If someone knows the reason of this problem, please reply it quickly.
