init_user_reserve | Initialise sysctl_user_reserve_kbytes.* This is intended to prevent a user from starting a single memory hogging* process, such that they cannot recover (kill the hog) in OVERCOMMIT_NEVER* mode.* The default value is min(3% of free memory, 128MB) |
init_admin_reserve | Initialise sysctl_admin_reserve_kbytes.* The purpose of sysctl_admin_reserve_kbytes is to allow the sys admin* to log in and kill a memory hogging process.* Systems with more than 256MB will reserve 8MB, enough to recover |
