Possible reasons: 1)Maximum allowed connections to DB or EIS is reached. You can apply CSN Note 719778 in order to check and resolve connection leaks. 2) Configuration to DB/EIS is wrong or DB/EIS is temporary unreachable. 3) Connections are not enough for current load.</P><P>I followed "1600085 - Dbpool of AS JAVA causing application related issues" so I set:</P><P>sysDS.maximumConnections=2500</P><P>sysDS.connectionLifetime=90</P><P>but I can't set </P><P>sysDS.maxTimeToWaitForConnection because it isn't for my release but I suspect that the problem is about it, so, what could I do?</P><P>The problem still remains.</P><P>Thanks a lot</P><P>Mario</P> Wed, 14 Jun 2017 06:58:21 GMT https://community.sap.com/t5/technology-q-a/j2ee-instance-server-node-problem/qaq-p/486801 mario_bisonti2 2017-06-14T06:58:21Z https://community.sap.com/t5/technology-q-a/j2ee-instance-server-node-problem/qaa-p/486802#M86352 <P>The problem was about MaxUserTasks on MaxDB</P><P>Setting it to 300 solved the problem</P> Thu, 15 Jun 2017 12:00:42 GMT https://community.sap.com/t5/technology-q-a/j2ee-instance-server-node-problem/qaa-p/486802#M86352 mario_bisonti2 2017-06-15T12:00:42Z
