what is the matter?

Can you provide more info any body can give more info?
Try to provide more details like
when that sesson is coming (is at startup or when u open GTM)
Is it stopping you any where?
Your environment is live or test?
Which language pack u r using?
Generally that error comes when your server is having virus.
