Description

The server startup is failing due to a 404 HTTP error from invocations of the internal/data/v1 service. The issue occurs because the startup process, which should be managed by the Equinox Container thread, is instead handled by a default Java thread. As a result, the Tomcat server startup and APIM component initialization run on the same thread. Since some APIM components rely on internal invocations that pass through the Tomcat server, but the Tomcat StandardEngine is stuck in the 'STARTING_PREP' state and unavailable, these internal calls fail with 404 errors. This causes delays in APIM component initialization, leading to the server startup thread getting stuck in a deadlock.

The server startup is not handled by the Equinox Container thread because OSGi framework events, which are responsible for initializing the APIM components, are not being processed properly. This issue could be caused by one of the following reasons:

  • OSGi components not being initialized correctly.
  • Resource Exhaustion
  • Security Permissions

Steps to Reproduce

  • Obtain the latest update level (117) of the APIM 4.2.0 pack.
  • Run the following two commands inside the APIM_HOME/repository/deployment/server/webapps directory to build the UIs (use the node -v 20):
npm install
npm run bootstrap
  • Please make sure that the node_modules folders are created in the webapps directory, as well as in the publisher and devportal directories.
  • Start the APIM server
