MySQL mysqldump exporting incomplete files?

I am trying to export a MySQL database from an Amazon Web Service Relation Database Service. I have tried connecting and exporting through MySQL Workbench and tried through command line in the EC2 server. But the tables exports still end up incomplete.

One table exports the first 5459 rows (1.1Mb) and then stops halfway through the row. another table exports the first 676 rows (7.7Mb) and then stops halfway through the row again, this table should have about 39000 rows.

I haven’t used Amazon Web Services before or Linux or MySQL, I normally work on Windows servers with Microsoft SQL. Has anyone had this error before or know what the cause could be?
