I found one of the DataSource in my domain was in Suspended state, giving "unable to allocate resources to the application" errors while testing it. I tried to untarget and re-target the DataSource so that it can create fresh connections to the database killing all pending connections and avoid restarting the servers but the untarget changes took so long to be activated so I navigated away from the page and tried to activate the changes one more time and it won't activate any changes that I made and the Error displayed on the console is as below. Restarting AdminServer did not solve the problem.
An error occurred during activation of changes, please see the log for details.
