Yeah, meminfo shows only 3G of memory, the tests needs about 4G to work well. The only problem was that I've screwed up the condition for that check and usually I don't test with restricted configs specifically. So this is expected behaviour. As long as we still have one machine where this tests run successfully we have sufficient coverage. When you verify this bug, can you pls check that it still runs successfully on at least one other machine?
It works well on another SNB machine(8G memory). Verified.Fixed.
Closing old verified.
