Comment 7 for bug 1838109

verification-done-bionic
verification-done-disco

Procedure:

* run: strings radosgw | grep max_connections
max_connections
max_connections value "%s" is invalid

run: sudo systemctl restart ceph-radosgw.target
...see no error in logs.
r
* edit /etc/ceph/ceph.conf
change:
    rgw frontends = civetweb port=70
to:
    rgw frontends = civetweb port=70 max_connections=1099329233823823823823832823832832
...see error in logs.

...restart with value in range (say, 1000), no error message.

* in the code there is no codepath setting this value without using the variable, internally: so seeing this behavior is evidence the feature is present.
