2206203904 maximum memory allowed in buffer cache (bufhwm) 65546 maximum number of processes (v.v_proc) 99 maximum global priority in sys class (MAXCLSYSPRI) 65541 maximum processes per user id (v.v_maxup) 30 auto update time limit in seconds (NAUTOUP) 25 page stealing low water mark (GPGSLO) 1 fsflush run rate (FSFLUSHR) 25 minimum resident memory for avoiding deadlock (MINARMEM) 25 minimum swapable memory for avoiding deadlock (MINASMEM)
