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:
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 ):

Unfotunately, today this situation has repeated with other group of users, the same scenario - after the attachment submission and few edits of the page, they are gone. A snippet from the log from that period of time ( a lot of that warnings ):

I'm counting on your help since I don't know it's more XWiki issue or maybe I misconfigured something.

I think you could be facing two kind of problems: one related with memory availability (the one causing attachements to "dissapear") and other one related to Lucene and some incompatibilities with Microsoft/ Microsoft Office files.
Concerning the problem related with memory availability, please, check this two links:
http://www.xwiki.org/xwiki/bin/view/FAQ/Howtoincreasethemaximumattachmentsiz... http://www.xwiki.org/xwiki/bin/view/FAQ/HowToSolveAJavaHeapMemoryError
I've already done that - I'm storing attachments 20MB size without any errors while uploading.
I'm not sure if this issus could lead to corrupted attachments or only to failures in the process. But I think it is worth to take them into account.
What scares me is the fact that even if something went wrong I have no visible warning or transaction's rollback. It's ending in the middle and confuses users.
If you're using MySQL, then it's a limitation of the default myisam engine, which doesn't have support for transactions. You should switch to innodb.
If you're not on myisam, then there's a bug in the storage.
Thanks for that info, indeed we had that default one enabled. Now we've switched to the innodb and we are monitoring our documents.
I hope that will solve our problem.
Thanks, Piotr
Does this add a reason to always use innodb as engine when running XWiki with MySQL as database? Thanks!
There are some recent quite interesting threads in devs list dealing with a proposal from Caleb. Just look for attachments in titles there. Sorry if I'm repeating this proposal!
Ok will do that.
Concerning Lucene errors. I do need to solve this also here. I've seeing also here issues with Lucene and Office files. Do you mind I try here with the attachments are causing you problems? Are there quite big? Could you send me a couple of them or make than available at any place? I can install on Monday recent XE snapshot in my dev box and you could upload them there, but I would already try them on my laptop.
I need to ask whether I could share that documents with others, if so I'll send you some examples.
Thanks!
Cheers,
Ricardo
