Also the message that I quoted in #2 is my variant of what is instead under: "if (bootverbose)" in standard FreeBSD code. So if you do a verbose boot, you should seem messages based on: if (bootverbose) printf( "proc %d (%s) failed to alloc page on fault, starting OOM\n", curproc->p_pid, curproc->p_comm); which would report the exact process that had the failure to allocate a page in a timely manor for handling a page fault. (Presumes you are not using vm.pfault_oom_attempts=3D-1 .) --=20 You are receiving this mail because: You are the assignee for the bug.=
