The first part is where I throttled the whole thing to 100 MBit in order to build up a traffic-jam ;)
When I released it, it jumped up immediately but suddenly it goes down (each pixel is one second) Playing around with min_free_kbytes didnt help. Where it goes up again I set lower_zone_protection to 1024000 and where it goes down I set it to 0 again and where it goes up the last time... guess..
Well I was only able to test this with 3500 sockets. I will try to jam up tomorrow to reach 5000 sockets to see if that is really the reason.

This issue has been tracked down more. This bug does NOT appear if I disable preemtive kernel.
Maybe this helps.
Yes, it may help - can you boot with profile=schedule and get the results for say, a 30 second period while the application is experiencing problems?
So:
start application wait till it hits slowdown readprofile -r ; sleep 30 ; readprofile > schedprof.out
and send schedprof.out, please?
Thanks, Nick
