Hi managers,
After my previous summary, a lot of people tell me to pay attention with
"lazy swap", since it will "delete" jobs picked to be swapped out when the
machine run out of swap space, and could be causes strange things to happen.
Now, we have found out the "crimial" process who take all our swap space,
and do the necessary. Specially set back vm-swap-eager to 1.
Thanks again for all folks kindly reply to me.
