Symptoms
The following appears in the atlassian-confluence.log:
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Row size too large (> 8126). Changing some columns to TEXT or BLOB or using ROW_FORMAT=DYNAMIC or ROW_FORMAT=COMPRESSED may help. In current row format, BLOB prefix of 768 bytes is stored inline. |
This is caused by the maximum allowed packet size of the MySQL server being too small.
The InnoDB Log File is too small, and must be increased.
Change the packet size configuration setting this to 64MB or larger.
http://dev.mysql.com/doc/refman/5.0/en/packet-too-large.html
In your my.ini (or my.cnf) file, add or modify the following line:
innodb_log_file_size=256M |
You may wish to adjust this value larger or higher depending on your specific installation. After making this change, restart Confluence and MySQL.
