Well, I found out the what, but not the why – another administrator
had put Word and PowerPoint attachments to email tickets, and when he elevated
their priority, OTRS stopped working. After deleting the attachments out of the
database, OTRS began working again. I did notice they were the only records in
the article_attachment table in the OTRS MySQL database that had a descriptor
of “application/msword” or “application/powerpoint”. I
highly recommend phpMyAdmin for routine MySQL database cleanup tasks:
