[xwiki-users] Attachments lost !

Hi, today I've noticed that something bad had happen to some of the attachments in my XWiki, here is a screenshot from one of the affected pages: http://i.imgur.com/p6Xs7.png Take a look, a couple of attachments have been uploaded but only one is displayed in the attachment tab. Person who uploaded them claims that yesterday they were ok, but today somehow they disappeared. It's weird that there is no trace of any operation on them after the uploading phase. I'm using XWiki Enterprise 2.5.32127 with MySQL data base (Server version 5.1.47). To add more context, last days my users started to add more attachements to their pages. Currently the database after the dump is around 200 MB large. Also looked at the logs and found several interesting fragments ( all of the log snippets are from the time this have been noticed ): 2010-11-18 09:03:09,355 [http://apps.man.poznan.pl:28181/xwiki/bin/download/Documents/Proposals/2009…] ERROR web.XWikiAction - Connection aborted Found a TextHeaderAtom not followed by a TextBytesAtom or TextCharsAtom: Followed by 3999 Found a TextHeaderAtom not followed by a TextBytesAtom or TextCharsAtom: Followed by 3999 Found a TextHeaderAtom not followed by a TextBytesAtom or TextCharsAtom: Followed by 3999 Found a TextHeaderAtom not followed by a TextBytesAtom or TextCharsAtom: Followed by 3999 2010-11-18 13:23:53,118 [http://localhost:28181/xwiki/bin/view/Projects/Opinion+Mining] WARN xwiki.MyPersistentLoginManager - Login cookie validation hash mismatch!
