Description of problem: SAP requires that vm.max-map_count is set to 2000000 (see http://service.sap.com/sap/support/notes/1496410 and http://service.sap.com/sap/support/notes/900929), the sap-netweaver tuned profile however only sets it to 1000000 Version-Release number of selected component (if applicable): tuned-profiles-sap-0.2.19-13.el6_6.1 How reproducible: always Steps to Reproduce: 1. check value in profile or run sysctl vm.max_map_count after profile has been activated 2. 3. Actual results: [root]# grep vm.max_map_count /etc/tune-profiles/sap-netweaver/* /etc/tune-profiles/sap-netweaver/sysctl.ktune:vm.max_map_count = 1000000 Expected results: [root@ls3229v4 ~]# grep vm.max_map_count /etc/tune-profiles/sap-netweaver/* /etc/tune-profiles/sap-netweaver/sysctl.ktune:vm.max_map_count = 2000000 Additional info:
