we have a live openerp instance running on the latest version of postgres. The problem is that the server is constantly maxing out memory. We have assigned 22gb of ram to the server and it has 20 assignable CPU cores and is running on a raid 10 array of SSD storage. The issue appears to be either with the postgres configuration or the openerp configuration or both. From what we understand, openerp is holding on the sessions for too long and postgres is essentially keeping lots and lots of 200mb chunks of ram in use for each of these sessions. If we reboot the server it quickly goes up to about 10gb memory usage and then creeps up to 22gb over the next half our to 4 hours depending on the usage on the server. We assume that it could be just a matter of running the openerp database queries through a proxy or working out what postgres database queries are inefficient or holding up too much memory. Or maybe looking at the general openerp configuration or postgres configuration in terms of how much memory is reserved for the number of users and database size. We have approximately 10-15 users and a database size of 8gb.
