Hello, We have our mendix app ( 8.6.2) deployed on Azure Cloud ( azure AKS) and doing load testing using cloud based load testing tool ( load ninja) . 1.Initially we simulated 150 concurrent logins, it failed with Connectionbus errors and after then we changed ConnectionPoolingMaxActive to 150 it started worked. 2. We then tried 500 concurrent logins and had to increase ConnectionPoolingMaxActive to 500 to make it work. 3 Now we are now trying to test with 550 concurrent Logins and its working. The mendix engine is shutting down. We tried increasing the memory from 3GB to 5GB but still the same. Pls provide some pointers as to why mendix engine is shutting down.  Can we enable additional debugging . We are getting below error in logs: org.eclipse.jetty.io.EofException at org.eclipse.jetty.server.HttpConnection$SendCallback.reset(HttpConnection.java:718) at org.eclipse.jetty.server.HttpConnection$SendCallback.access$300(HttpConnection.java:678) at org.eclipse.jetty.server.HttpConnection.send(HttpConnection.java:536) at org.eclipse.jetty.server.HttpChannel.sendResponse(HttpChannel.java:836) at org.eclipse.jetty.server.HttpChannel.write(HttpChannel.java:891) at org.eclipse.jetty.server.HttpOutput.write(HttpOutput.java:240) at org.eclipse.jetty.server.HttpOutput.write(HttpOutput.java:216) at org.eclipse.jetty.server.HttpOutput.write(HttpOutput.java:515) at org.apache.commons.io.IOUtils.copyLarge(IOUtils.java:2315) at org.apache.commons.io.IOUtils.copy(IOUtils.java:2270) at org.apache.commons.io.IOUtils.copyLarge(IOUtils.java:2291) at org.apache.commons.io.IOUtils.copy(IOUtils.java:2246) at com.mendix.external.connector.ResourceRequestHandler.processRequest(ResourceRequestHandler.java:57) at com.mendix.externalinterface.connector.RequestHandler.doProcessRequest(RequestHandler.java:40) at com.mendix.external.connector.MxRuntimeConnector.processRequest(MxRuntimeConnector.java:63) at com.mendix.basis.impl.MxRuntimeImpl.processRequest(MxRuntimeImpl.java:945) at com.mendix.m2ee.appcontainer.server.handler.RuntimeHandler.service(RuntimeHandler.java:42) at javax.servlet.http.HttpServlet.service(HttpServlet.java:790) at org.eclipse.jetty.servlet.ServletHolder.handle(ServletHolder.java:867) at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:542) at org.eclipse.jetty.server.handler.ScopedHandler.nextHandle(ScopedHandler.java:255) at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:1588) at org.eclipse.jetty.server.handler.ScopedHandler.nextHandle(ScopedHandler.java:255) at org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1345) at org.eclipse.jetty.server.handler.ScopedHandler.nextScope(ScopedHandler.java:203) at org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:480) at org.eclipse.jetty.server.session.SessionHandler.doScope(SessionHandler.java:1557) at org.eclipse.jetty.server.handler.ScopedHandler.nextScope(ScopedHandler.java:201) at org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:1247) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:144) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:132) at org.eclipse.jetty.server.Server.handle(Server.java:502) at org.eclipse.jetty.server.HttpChannel.handle(HttpChannel.java:364) at org.eclipse.jetty.server.HttpConnection.onFillable(HttpConnection.java:260) at org.eclipse.jetty.io.AbstractConnection$ReadCallback.succeeded(AbstractConnection.java:305) at org.eclipse.jetty.io.FillInterest.fillable(FillInterest.java:103) at org.eclipse.jetty.io.ChannelEndPoint$2.run(ChannelEndPoint.java:118) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:765) at org.eclipse.jetty.util.thread.QueuedThreadPool$2.run(QueuedThreadPool.java:683) at java.base/java.lang.Thread.run(Unknown Source)           Thanks.
