When attempting to save to the Management Server through AM/EM/PM consoles you receive the below error:-
'Connection error : args )'
This is caused because a connection cannot be succesfully made to the SQL database, once it has ran out of free disk space.
If the space is completely used up then a connection cannot be established. Space needs to be allocated to the SQL instance / database itself. This will then allow configurations to be created, edited or even deleted.
