for all current MariaDB version, 'Too many connections' format differ from expected.
protocol expect :
i.e. if protocol capability is CLIENT_PROTOCOL_41 is set, and all client have that since a long time, SQLState must be send.
problem is that we receive 'Too many connections' error in pre CLIENT_PROTOCOL_41 format.
example :
+--------------------------------------------------+
|
| 0 1 2 3 4 5 6 7 8 9 a b c d e f |
|
+------+--------------------------------------------------+------------------+
|
|000000| 17 00 00 00 FF 10 04 54 6F 6F 20 6D 61 6E 79 20 | .......Too many |
|
|000010| 63 6F 6E 6E 65 63 74 69 6F 6E 73 | connections |
|
+------+--------------------------------------------------+------------------+
|
Error code when CLIENT_PROTOCOL_41 is set MUST have the SQLState send.
