<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"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">WARN [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (default task-224) SQL Error: 0, SQLState: null<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I am using MySQL Database.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Another thing I noticed with this is that I listen to this JMX for metrics:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">jboss.as.expr:subsystem=datasources,data-source=MySQLDS,statistics=pool<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">for the ActiveCount metric<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"><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>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Kind Regards,<br>
