I use aws ec2 ubuntu linxu 20.04. (free-tier) Front-end developers made the mistake of requesting api dozens of times a second. After that, the following error appears every time you connect to the server.
This error prevents ssh from accessing the server.
I tried to increase the limitations such as max user processes and real-time priority, but it is already set to maximum.
What should I do in this situation? I need a lot of help.
