I am hosting my openerp 7 on a linux server running centos. Whenever i start my openerp server and run it, The server memory keeps increasing from 5% to 25 - 30% and the server become really slow. Then i need to force restart my server to get things back to normal. Is that something to do with my server configuration or the openerp in general itself is like this? Can some experts suggest some solution for this?
