2.  What is the nature and description of the request?
Implement SO_KEEPALIVE in network calls

3.  Why does the customer need this? (List the business requirements here)
Customer's RHDS being affected by lingering TCP connections that are not
correctly closed (refer to https://access.redhat.com/kb/docs/DOC-44459).
From RFC 1122:
 A TCP keep-alive mechanism should only be invoked in
 server applications that might otherwise hang
 indefinitely and consume resources unnecessarily if a
 client crashes or aborts a connection during a network
 failure.
With this implementation, RHDS would be more resilient to
misconfigured/problematic clients, at a minimum cost.

4.  How would the customer like to achieve this? (List the functional
requirements here)
Implement SO_KEEPALIVE in network calls.

5.  For each functional requirement listed in question 4, specify how Red Hat
and the customer can test to confirm the requirement is successfully
implemented.
# netstat -tnpo
 ...
 tcp        0      0 10.66.129.184:40223         10.64.10.12:636
ESTABLISHED 1337/ns-slapd         keepalive (2740.13/0/0)

6.  Is there already an existing RFE upstream or in Red Hat bugzilla?
No.

7.  How quickly does this need resolved? (desired target release)
9.x

8.  Does this request meet the RHEL Inclusion criteria (please review)
Yes

9.  List the affected packages
RHDS

10. Would the customer be able to assist in testing this functionality if
implemented?
Yes.
