we have zram active on all nodes but tweaked the 'swappiness' value to 0 - the default is 65. the higher the number, the more likely the kernel swaps out. if set to 0 zram is only used if the is no other possibility. ofcourse: if swapping begins, the box freezes for some seconds but it does not die. the kernel likes to swap out processes which are not in use, e.g. uhttpd or dropbear. olsrd or other active processes are very unlikely to be swapped - the kernel is smart somehow 8-) bye, bastian _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
