<p class="MsoNormal"><span lang="EN-US">We have an architecture of 3 nodes with Shibboleth IDP 3.4.4 over a Tomcat 8.5; we also have Apache HTTPD 2.4 as webserver proxy.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">Recently, when we have to recover from a database crash, the IDPs have more than 500 requests/minute to be processed.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">We believe that somehow, apache is unable to process all the request so they are not getting to Shibboleth.<o:p></o:p></span></p>
