Ideally also if you can add some details (eg. configuration of
your KeycloakDS datasource, what Keycloak functionality you used.
if number of connection is 18 from the beginning and then it's
same for longer time or if it's 0 from the beginning and then it
slowly increases etc.)<br>

Thanks,<br>

<p class="MsoNormal"><span style="font-size:11.0pt">Hello, after
upgrading to Keycloak 2.1.0 I have started to see that
Keycloak is logging warnings like this:<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">and I
constantly see this being 18 despite having nearly no
Keycloak usage. So it’s making me to think that there is a
connection leak in Keycloak, because I should not see 18
active connections, when there is no load on Keycloak.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">Could you
please have a look at this? I don’t really remember seeing
this issue in Keycloak 2.0.0, so I’m just guessing it could
be just 2.1.0 issue as well…<o:p></o:p></span></p>
