Archive Task not functioing, event ID error 3310

I'm currently having a bit of trouble with a version 7 installation whereby archiving is not functioning.
Every 10 minutes event ID 3310 is logged against the Enterprise Vault log. I have tried the suggestion of modifying the SMTP value as suggested in a previous forum thread but this has not resolved the issue.

I have run a DTRACE on the archiving task and have noticed this rather strange output from a my verbose logging:

What is going wrong that it goes from saying all is successful to then failing? I have attached the full DTrace output for those interested.
Any help would be much appreciated.
Thanks
