I have the same problem. Currently I'm using Ubuntu 14.04 64bits. I have 4GB of RAM and no swap. If I open too many apps and memory usage goes to 100%, the system completely freezes.
Before 14.04, I was using 8.04 32bits and this problem never happend. If all the memory was used, new apps would just crash when trying to malloc but the system will still remain solid stable. My system is: Intel Core 2 Duo, 4GB RAM, nVidia GPU and Ubuntu 14.04.4 LTS Tried already to increase /proc/sys/vm/min_free_kbytes to 270336, but the problem persists. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/159356 Title: System freeze on high memory usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/159356/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
