Abstract
According to one embodiment, it is determined whether data stored in a compressor pool exceeds a first predetermined threshold, the compressor pool being a fixed-size memory pool maintained in a kernel of an operating system. The compressor pool stores a plurality of compressed memory pages, each memory page storing compressed data pages that can be paged out to or paged in from a persistent storage device. The compressed memory pages are associated with a plurality of processes. A memory consumption reduction action is performed to reduce memory usage, including terminating at least one of the processes to reclaim a memory space occupied by the process, in response to determining that the data stored in the compressor pool exceeds the first predetermined threshold.
