ps_send_chunk() stops working after sending random sized packets about packet-io-engine HOT 6 CLOSED

I tested and stumbled upon this problem too - my goal is a performance testing application with random packets for our network - and I see the same issue, if packet is random size - it doesn't work after a short while.

Any word from the maintainers of the project?

Ok, I have confirmed the same problem with modified pspgen. We will look into that.

achimnol - any updates on this?

Seems to be fixed now. I will run test for the whole night and reopen it if the problem occurs again.

After all night test, the problem has occurred again. :(
This time, it does not stop completely but only a single interface is stopped among 4 interfaces in the system.
And a SandyBridge server with 8 interfaces does not show this problem at all while two Westmere servers with 4 interfaces do.
We still need to investigate this problem further, but I'm going to focus on other stuffs first. Any help will be appreciated!

The last patch seems to work well, sustaining full load more than 7 hours without any problem.
