[xwiki-users] BUG: Attachments become empty after a while

Hi, I'm facing some trouble with attachments becoming empty (zero bytes) after some time they were uploaded. I'm using XWiki Enterprise 2.4.30451. I've searched the mail archives and it seems to exist a bug in the cache coherency. I could not find anything related on JIRA. My -Xms and -Xmx are both 768m. Although my max packet size on MySQL is 20Mb for attachments, the files that are becoming empty are docs, pictures and xls's of a few Kbytes. Can someone point me some cause and solution on this please? Regards, Ramon Gomes Brandão
