[-- Attachment #1 --] During heavy postgresql load (pgbench), /var/log/messages registers (multiple times) the following message: "Approaching the limit on PV entries, consider increasing either the vm.pmap.shpgperproc or the vm.pmap.pv_entry_max sysctl" I'm increasing both, but no matter what I increase them to, after a short time they again get increased by the system (???). The values are currently: vm.pmap.shpgperproc: 1134 vm.pmap.pv_entry_max: 8000000 But the last sysctl setting, verified by retrieving it from my shell command line history, is that I set vm.pmap.shpgperproc to 800. Is this normal, and what are the common settings for these values? The machine is 2x4-core, currently 4 GB RAM (which will increase to at least 6 GB), amd64, running postgresql, php and apache.
