we have 80Gb of real memory. if i did not mention, we have Oracle DB on the system, and as i know usually it's hungry for computational memory.
i have saved vmstat output from 2 days ago, when system was paging, but without I flag.
any suggestions on the stats below?
Code
# vmstat -wt 1 50
System configuration: lcpu=12 mem=81920MB ent=4.15
kthr memory page faults cpu time
