X-Git-Tag: v185~6 X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=a52289f7f50b3e851bf831cb692eea9ff02e9b50;hp=a52289f7f50b3e851bf831cb692eea9ff02e9b50 udev: lower the starting children_max -> drop the minimum required RAM from 23mb to 5mb Udev was the limiting factor for us on low-RAM systems. Given an average RSS of 180kb, 128 workers would require ~23mb of RAM. Now, please consider what happens when there is only, say, 15mb free. Udev protects itself from OOM, and the kernel can do nothing but panic. 28 workers * 0.18mb = ~5mb. This change should not affect more powerful systems much, given that they still get the addition from the amount of RAM. ---
