Attachment missing,When i send schedule email campaign

Hi Everyone,
Attachement is missing, when i send schedule email campaign from campaign module.
First i create one Email-Template and in that email template i attach one document as pdf.After that i select the same Template while creating email campaign but when i click schedule email then email receive at their given time,but attachment is missing from it.

Please help me if you have any idea.
Thank you in advance.

If the behavior is different only when sending from Campaigns, then I recommend checking the php.ini option for CLI PHP, which is different from the Web server PHP.

If this is your problem, you probably have a FATAL error in your php_errors.log.

Thank you for your reply.
Ok, i check once and get back to you
