If you're using MySQL database, you may encounter the following issue:

java.lang.RuntimeException: There was a problem evicting or flushing a PluginData object
at com.atlassian.confluence.plugin.persistence.hibernate.HibernatePluginDataDao.saveOrUpdate(HibernatePluginDataDao.java:65)
caused by: net.sf.hibernate.exception.GenericJDBCException: could not insert: com.atlassian.confluence.plugin.persistence.PluginData#3375106
at net.sf.hibernate.exception.ErrorCodeConverter.handledNonSpecificException(ErrorCodeConverter.java:90)
caused by: com.mysql.jdbc.PacketTooBigException: Packet for query is too large (3063507 > 1048576). You can change this value on the server by setting the max_allowed_packet' variable.
at com.mysql.jdbc.MysqlIO.send(MysqlIO.java:2691)

To resolve this issue, simply increase the max_allowed_packet setting in your MySQL config to 4M using the command line shell as follows:

shell> mysql --max_allowed_packet=4M
