Jira shows: Cannot attach file xxxxxx.pdf: Unknown server error (500).

I am able to attach any other type of files.

1. To be able to attach files, your JIRA administrator must have enabled file attachments.

2. Make sure file attached has not exceeded 10 MB> By default, the maximum size of any one file is 10MB, although this limit can be customised by your JIRA administrator.

3. File names cannot contain any of these characters: '\', '/','\"', '%', ':', '$', '?', '*'.

Got a similar problem, but none of Raul's hints help. A colleague tried to attach a file "FAQ.pdf", which is 170 kB in size. And he gets Reinhard's error message. Odd enough it's also a PDF. I've got admin rights and - strange enough - I can attach that file. But the colleague can't. How can that be?

Reinhard, my PDF contains JPEG images - yours, too?
