Requests for the Enterprise Server administration get scheduled to SEPs. It is possible that all SEPs could be in use by application code. This scenario can prevent an administrator accessing the server.

V6 of Server EE (Enterprise Server) introduced the concept of administration SEPs. Admin SEPs are reserved for use by the ESMAC administration system and hence their availability is not impacted by application code. This will allow administrators to access ESMAC even when an application is in a hung state and not accepting new requests.

The feature is enabled by using an environment variable:

ES_ADMIN_SEPS=1

This will specify 1 admin SEP but it can be configured higher if this is needed (e.g. on a more active system).

Server EE 6.0 SP1 defaults to 1 admin SEP even if the environment variable is not specified.
