Shouldn't that be already visible in the ingo's sysrq-t dump, no? There:

  http://marc.info/?l=linux-kernel&m=121182099131520&w=2

There are many sys_accepts at least (if I understand that dump at all). 
There were some ip_local_outs there as well, which made me wonder if the 
totally innocent looking commit 1ac06e0306d0192a7a4d9ea1c9e06d355ce7e7d3 
(ipsec: Use the correct ip_local_out function) has something to do with 
this (I definately don't understand that part at all).
