Details:

Dear Experts 
We use lwip version 1.40_V2_2 library for network  in our zynq 7000 based
project.
Zynq 7000 is a product of Xilinx company .
It works perfect when we test it for short period of time. 
But following error occurred on long time test:
Our system runs into an exception ( called Xil_PrefetchAbortHandler) and we
could not send any new packet to our zynq board. 
This bug is the result of receiving a lot of packets or receiving a single
packet after a while the connection was established.
We do not use freeRTOS and run our program in bare metal mode.

Do you know how we could resolve it?
BR
Mohandes,
