I successfully installed the Sentry on AWS EC2 sever, and I can receive error event from my project. But the EC2 server will crash after about 1 day. I cannot ssh into the server, and I cannot access the Sentry web page. But all work well if I stop and start the server from the AWS console.
I tried to install the Sentry on a standalone server with Sentry being the only service on it, and it works well currently. But there are some CPU usage spike seen from the monitoring. I guess it may not be actually “crash”, it is the high CPU usage that stuck the EC2.
So I suggest you try the Sentry installation on a new server to see if it helps you.
