This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig526DE873EF681C583AFA92BA Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable 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. --------------enig526DE873EF681C583AFA92BA Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFH1qp+ldnAQVacBcgRAh7HAKCBCpa/5y/6wMztLQqa8buKei55OgCgge66 MxMxTvjS73S0CDSOqY4+Ky0= =hJaW -----END PGP SIGNATURE----- --------------enig526DE873EF681C583AFA92BA--
