This will only happen to attachments which fail to upload, I'm guessing this only
happens on the
largest attachments. You will find a lot more information inside your tomcat log. You
might try
searching the logs for "XWikiHibernateAttachmentStore".

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.
But, please, why does the failure happen once in a bunch and not always?
Thanks!
