Spring Boot REST API startup delay - mysql

Question

When I start up my Spring Boot API (which is running in a Docker container), there's a very long delay between the RepositoryConfigurationDelegate step and the PostProcessorRegistrationDelegate step. I've modified the dates below for readability, but they reflect the roughly 2.5 hour delay I'm seeing:
2023-01-17 08:00:00.123 INFO o.s.d.r.c.RepositoryConfigurationDelegate - Finished Spring Data repository
scanning in 97 ms. Found 24 JPA repository interfaces.
2023-01-17 10:30:00.123 INFO o.s.c.s.PostProcessorRegistrationDelegate$BeanPostProcessorChecker - Bean
'methodSecurityConfig' of type [com.deloitte.tve.MethodSecurityConfig$$EnhancerBySpringCGLIB$$90e69ca] is
not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)
2023-01-17 10:30:00.456 INFO o.s.b.w.e.t.TomcatWebServer - Tomcat initialized with port(s): 8080 (http)
Any idea what would cause this kind of delay and/or how to troubleshoot it?
Sometimes the Spring Boot API process startup stalls in a similar manner when I run in my local dev environment. Then when I hit [enter] in the terminal it proceeds again.
But in this case, Spring is running in a Docker container. I can shell into the container. From there, is there a way to remotely shell into the startup process itself and essentially do the same thing I do in my dev environment (hit [enter]) to trigger the startup to proceed if/when it hangs?
