Hi, All
I agree with Minchan and can't think this is a real fix....
Andrey, I'm now trying your fix and it seems your fix for oom-killer,
'skip-zombie-process' works enough good for my environ.

What is your enviroment ? number of cpus ? architecture ? size of memory ?
Processort: AMD Phenom(tm) II X6 1055T Processor (six-core)
Ram: 8Gb
RHEL6, x86_64. This host doesn't have swap.

It hangs up fast. Tomorrow I will have to send a processes state, if it will be interesting for you. With my patch the kernel work fine. I added debug and found that it hangs up in the described case.
I suppose that my patch may be incorrect, but the problem exists and we should do something.
