It should be listed.

I think it is caused by forking process bomb by msgctl11 on LTP. 
We can refer old discussion(http://osdir.com/ml/linux-kernel/2009-07/msg00926.html)

I think this issue can be solved by 
dynamic reclaim throttling patch which is making by Rik.

After he merges it, Let's test again.
