Symptoms

When attempting to connect to EM  using "http://<HOST>:7001/em" for IDM 11.1.1.2, it fails with 503--Service Unavailable error as follows:

Note: The existence of the 503 status code does not imply that a server must
use it when becoming overloaded. Some servers may wish to simply refuse the connection.

NOTES:

• EM application worked normally after install.
• After 2 weeks of operation the EM application stopped working coming back with the HTTP-503 error. There were no configuration changes done to the IDM domain or AS Instance.
• The issue is not resources related as the issue reproduces even when just the Admin Server is up and there are no other components running.
• The FMW Control does start as it responds to the requests but then fails with the 503 error.
