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.
