v2.2.0 heavy writing at raid5 array kills processes randomly, including init.
Normal user can force random processes to out of memory
situation when writing stuff at raid5 array. This makes the raid
I get 'Out of memory for init. ' etc. with following simple command:
dd if=/dev/zero of=file
Repeatable, file is between 100-200M after dd gets killed.
I guess this killing action seems to be triggered by swapping.
