A few race conditions in the scheduler were fixed, which could result in CPUs goi= ng idle with work to do. In some sense, setting steal_thresh=3D1 can work aro= und these problems. > kern.sched.steal_thresh=3D1 > machdep.idle=3Dmwait Are both settings needed? --=20 You are receiving this mail because: You are the assignee for the bug.=
