<p class="MsoNormal"><span lang="EN-US">Hi Community,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">We have a midpoint system with 3 nodes. We use the default maxPoolSize=40 for all 3 nodes. At peak time, about 30 requests (or more) per minute are sent to midpoint via RESTapi and we encounter very often the error
</span><b>Java.sql.SQLTransientConnectionException: HikariPool-1 – Connection is not available, request timed out after 30000ms</b><b><span lang="EN-US">.
</span></b><span lang="EN-US">Maybe it’s because of running out of free connections? Does anyone have the experience with large amount of requests and multiple nodes? What is the best practice to avoid running out of free connections? How can I get more information
about the waiting/idle DB connections?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Thank you very much for your help in advance!<o:p></o:p></span></p>
