We recently encountered the issue that the checkbox that states "Geodatabase is accepting connections" (in Database Properties --> Connections tab) was found to be unchecked and the Geodatabase indeed did not allow any new connections.
Once discovered it was an easy fix, we just connected as SDE user an checked the box. The question is how did it get unchecked?
We can narrow down the time window to when it must have become unchecked based when scheduled tasks started to fail, and can use Oracle audit to verify that no connection as SDE was made during that time window.
Has anyone experienced this before? What factors could trigger it? Is this a known bug?
