This is almost definitely caused by the attachment not saving properly. Despite the
failure to save,
the cache holds the attachment for a time but eventually it is cleared and the attachment
appears to
vanish. The cache inconsistency is fixed as of 2.5M1.
As far as the attachment not saving properly and showing no sign, usually we start by
blaming mysql
max_packet_size. If you upload an attachment about the size of the largest attachment you
ahve
uploaded so far, check the tomcat log and you will probably see an exception trace. This
will tell
you what caused the problem.

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
