from LINT on 4.1.1-STABLE (built last night) >>> Set the number of PV entries per process. Increasing this can stop panics related to heavy use of shared memory. However, that can (combined with large amounts of physical memory) cause panics at boot time due the kernel running out of VM space. If you're tweaking this, you might also want to increase the sysctls "vm.v_free_min", "vm.v_free_reserved", and "vm.v_free_target". <<< Are any guidelines available here? If I increase the PMAP_SHPGPERPROC value by 200 (to 400), what should I increase the vm.v_free_* values to? Currently they are: vm.v_free_reserved: 164 vm.v_free_min: 481 vm.v_free_target: 1607 Any pointers greatly appreciated.
