Compared with
a) vmstat-4.10.17-10Gb.log (OK with swapping) and b) vmstat-10Gb.log (NOT OK - System Unresponsive)
The si/so is low in both files. And si/so in a) is higher than that of b), so the problem may be we swap less than before?
The bi is kept high in b). I guess we encountered thrashing for file pages.
