Description of problem: Fedora freezes on high memory usage, or system goes almost unresponsive Version-Release number of selected component (if applicable): How reproducible: always Steps to Reproduce: 1. Use up all system memory in your computer. I do this by opening up high ram usage tabs in firefox 2.Watch your computer freeze up 3. If the computer unfreezes, check for high Cpu load averages, and possibly low swap usage Actual results: Computer freezes on high ram usages, and cpu load average goes way up Expected results: Computer does not freeze. Either OOM killer kills non volatile processes, or more processes are swapped Additional info: Tested E6400 with 2gb ram/ 2gb swap I5-520m with 4gb ram/ 4gb swap Info on how to debug behaviour like this would be appreciated
What I believe happens is that all RAM is used first, then swap is used. This should really be, when ram is about 3/4 full, we start swapping everything that won't effect user performance so it is a lot harder to fill up ram
