- A process that so far requires relatively few memory calls. XFS filesystem operation, which in turn is necessary if you need to perform one share to continue.
- The memory maintenance subsystem is trying to fill the allocation, but Where found, in turn, there is no memory. He answers first, trying direct fetch (forced deletion of memory pages), from then if which doesn’t generate the recommended free memory, it’s time for the default out-of-memory (OOM) killers.
- OOM recommends that the killer judge his victim and destroy him.
