Servicedesk 8213 version error fetching mails and merging requests

Dear all,
 
Since i updated SD to latest version the mail fetching is not working. It works for a while and it stops suddently. It happens each time an e-mail containing the requuest ID in the subject enters the mailbox.
 
Also when i try to merge two or more requests i get an error:
 
"FAILURE :Problem while trying to merge this threaded request with the selected request."
 
I think the mail fetching error could be related to this as the system is not able to merge incoming mails containing an existing request id in the subject with the original request.
