Bug #36540 CREATE EVENT and ALTER EVENT statements fail with large server_id.
This is a usability bug, that makes the DBA life unnecessarily hard. The reason for having a large server_id is because a DBA might want to use the IP address as server ID, to make sure that there are unique IDs, and to have an easy way of identifying the server through the IP.
All is well until you mix the server_id assignment with event creation:
select version();
+-----------+
| version() |
+-----------+
| 5.1.32 |
+-----------+
1 row in set (0.00 sec)
set global server_id =inet_aton('192.168.2.55');
Query OK, 0 rows affected (0.00 sec)
select @@server_id;
