If /etc/sysctl.d/sap_hana.conf contains net.core.rmem_max and net.core.wmem_max, the values of these parameters might be lower than those mentioned in SAP note 3024346. Due to the precedence rules for sysctl, this will cause lower than necessary values to be set for NetApp.

Because of this, we should better ensure that these parameters are not present in file /etc/sysctl.d/sap_hana.conf if NetApp is used, and also ensure that the correct settings are in effect.

See also #196 (comment) and #813 .
