I'm getting the above mentioned error when backing up with ZRM, which is using mysqldump for backup.

mysqldump --opt --extended-insert --single-transaction --create-options --default-character-set=utf8 --user="<username>
" -p --all-databases  > "/nfs/backup/mysql01/dailyrun/20091216043001/backup.sql"

mysqldump: Error 2020: Got packet bigger than 'max_allowed_packet' bytes when dumping table `TICKET_ATTACHMENT` at row: 2286

I have increased the size for 'max_allowed_packet' to be 1G in /etc/my.cnf which is the server setting and for the client side setting I've set it by running this command:

mysql -u<username> -p --max_allowed_packet=1G

And I have verified that on the client and server side they are of the same value.

This is to check the client side value according to this forum posting http://forums.mysql.com/read.php?35,75794,261640

mysql> SELECT @@MAX_ALLOWED_PACKET
    -> ;
+----------------------+
| @@MAX_ALLOWED_PACKET |
+----------------------+
|           1073741824 |
+----------------------+
1 row in set (0.00 sec)

And this is the check the server value setting.

mysql> SHOW VARIABLES
| max_allowed_packet              | 1073741824                                               |

I have ran out of ideas, and tried searching within expert exchange and googling for solutions but so far none has worked.

Please advise, thank you.
