Hi my boss has asked to look into multiple variation of this message we are getting in our monitoring scripts of the kernel messages.

Aug 30 01:00:28 OurServer kernel: Ack 1233895432 out of 1233898328:1233917320

I do not have a clue what this means and my old friend Mr google has not enlightened me in any way. They do happen sparadically throughout the day but %80 happen around 1 am

What exactly am I looking at here. I thought this would be something to do with the TCP stack, but not sure where to go from there
