Here is exact link from Interactive Brokers site that lists current limitations:
 
Note that they are adding new limitations. Previously there was only 60 request per 10 minutes limit that I mentioned below but now as you can see there are more limits.

Backfill throttling is a  LIMITATION IMPLEMENTED BY INTERACTIVE BROKERS inside TWS.
=======================================================================
 
Interactive Brokers allows the following MAXIMUM amount of backfill:
Sixty 5-day segments per any 10 minutes period.
 
If you download say 30 days for every symbol it equals SIX 5-day segments
per symbol, effectivelly leading to only 10 symbols (30days each) during any 10 minute period.
 
If you reach the limit Interactive Brokers will send error 162 (MAXIMUM limit reached - Throttling),
until 10 minute segment passes without allowing any subsequent backfill.
 
Only AFTER 10 minutes you will be allowed to backfill again.
 
It is really NOT mine invention - it is Interactive Brokers policy - please complain to them.
There are zillions of
