Hello, Recently I have enabled statistics module which works pretty nice. One thing though I have noticed in xwiki log file is the following exception occurring periodically

Could someone tell if it's a serious issue and which type of error it identifies: configuration error or bug in statistics module? We are running XWiki Enterprise 2.2.4.28034 Regards, Roman -- View this message in context: http://xwiki.475771.n2.nabble.com/Data-too-long-for-column-XWV-UNIQUE-ID-err...
