Why are BMan hardware buffers disappearing under high load on 10G with fragmentation enabled?

Why are BMan hardware buffers disappearing under high load? I am using a P4080DS and under high load on the 10G ports, with ip fragmentation enabled on the TX port, BMan buffers seem to never be released by the hardware.

 

The issue appears at really high load and only when I have fragmentation on the TX port. No error interrupts seem to be triggered anywhere and the enqueue to hardware doesn't report anything.

 

Thanks,

Mihai
