I've tried to set vm.min_free_kbytes to 6% of my total physical RAM, divided by the number of cores as it is said there https://askubuntu.com/questions/41778/computer-freezing-on-almost-full-ram-possibly-disk-cache-problem, but I decided to keep vm.swapiness at its default (60), because I was going to tune up zram. And then I had installed zram-config package, opened /usr/bin/init-zram-swapping file with my text editor and had changed this string mem=$(((totalmem / 2 / ${NRDEVICES}) * 1024)) to this: mem=$(((totalmem / 2 / ${NRDEVICES}) * 5 * 1024))
Then I had rebooted and tested this all with "stress -m 4 --vm-bytes=1G". This all was happening on my one core 2Gb x86 Lubuntu 16.04 notebook. Seems it works. -- 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: When DMA is disabled 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
