We upgraded from v9.1.1 to the 2019.2 on a test server and have the following issues...
1. TeamCity Web UI takes forever to initialize components, this may be due to # 2.
2. Several of the OpenJDK Platform binary processes are hitting very high CPU and killing the server. This seem to be related to the TeamCity Server service because if I stop that service, then the CPU drops. Or do these processes do some work on upgrade and we should just allow them to complete?
3. The SQL Server process is also using a lot of CPU. We use this for our database.
4. In the TeamCity UI, we no longer have buildAgents available. Agent has unregistered (will upgrade).
Any thoughts on how to resolve these issues?
