This is a major design flaw of the current attachment storage model. As stated in a previous mail, handling attachment consumes about 27 time the size of the attachment, so 90M * 27 ~= 2.5G. This needs to be fixed ASAP. In the meantime, you can either increase the heap size to more than 2.5G, or request an sql dump from the myxwiki farm admins. -- Sergiu Dumitriu http://purl.org/net/sergiu/ _______________________________________________ users mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/users
