We've recently changed the server Moodle is hosted on and upgraded to Moodle 2.8. When I try to back-up, restore and import from a few of the courses on the new server I get a dmlwriteexception. When I turn debugging on I get the error below. This only happens on two of the larger courses. I've done a bit of research online to see about the issue, it seems to be something to do with MySQL, but I haven't been able to find a fix - has anyone any ideas?
