Qlik sense deploy on AWS

[WangFei]

hello everyone 

I have installed 7 EC2 servers on AWS, including 1 central node, 2 scheduler nodes, 3 product nodes, and 1 development node. When I installed the sub nodes on the central node, from the screenshot nodes interface, it can be seen that the services of each node can start normally. However, there is an issue where these sub nodes often automatically disconnect and reconnect. It is strange that the QS service in the node server has been running normally. May I ask experts, based on your experience, what is the reason for this phenomenon and how to modify the configuration to maintain the stability of the node state?

Thank you！

Hello @WangFei 

Given your setup description,  could it be that you are still on 100 max connection for the database? You should have 120 per node. So in your case 840.
