+<section>Indicates whether SO_KEEPALIVE is enabled on Sockets. The keepAlive
+mechanism is used to detect when clients disconnect unexpectedly.  A <i>keepalive
+probe</i> is sent to the client if a long time (by default, more than two
+hours) passes with no other data being sent or received.    <ph conref="adminconrefs.dita#prod/productlowercase"></ph>.drda.keepAlive
+is used to detect and clean up connections for clients on powered-off machines
+or clients that have disconnected unexpectedly. </section>
+<section> If the property is set to <codeph>false</codeph>, <ph conref="adminconrefs.dita#prod/productshortname"></ph> will
+not attempt to clean up disconnected clients. keepAlive might
+be disabled if clients need to resume work without reconnecting even after
+being disconnected from the network for some time. To disable keepAlive probes
+on Network Server connections, set this property to <codeph>false</codeph>.</section>
