When sending multiple continuous update and/or read requests to the session service, the endpoint occasionally returns a 404. This issue appears to be exacerbated during functional test runs, possibly due to the frequency of configuration changes. This can be demonstrated using the tests in TestSessionService that has been marked with this issue number, using IntelliJ. Note that the test in question is long running, and should be used for manual testing only.
This could potentially cause problems in a dev-ops environment, and can also can cause sporadic failures during functional test runs.
