AXI DMA stopped working after 7 hours of operation in xapp1305 + 1588

Hi 

I have a custom design based on Xilinx xapp1305 reference design, where I added a 1588 timer and enabled the 1588 feature from the AXI 1G/2.5G Ethernet subsystem

 

It is all working fine until after around 7 hours of operation, when internet stopped working and the ifconfig shows the overrruns happened on the RX path. I dumpped /proc/interrupts and found that the rx_irq of the AXI DMA for the AXI Ethernet subsystem stopped happening. 

 

I am wondering if anyone has the similar experience. So far I have no clue why this is happening. On the other hand, the original xapp1305 doesn't have this problem.

 

Thanks

don't know if it's related by i used VDMA and often they stopped working. 

I since then included in my programs a check to continuosly check if they are running and just in case re-start them
