SSL SYSCALL error when syncing multiple tables

[rbhalla]

When I attempt to sync multiple tables I'm getting the following error after a few tables have finished syncing:

Traceback (most recent call last):

From the stack trace you can see that the table campaign_members is failing. If I try and run this table individually, it does work.

Not sure I understand enough about Redshift's cursors to debug, anybody encountered this before?
