From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Getting sluggish and then freezing sounds like RAM full. Earlyoom might help, it kills the abuser quicker than the in-kernel but notoriously slow-triggering solution.
And prelockd might help too; it reserves place for some libraries in memory, so they don't get involved in the freeze haze.
Never knew about prelockd, seems like a pretty neat and useful idea, thanks!
