Retrieving topology records on version 4.5.9 3-DNS

Is there a limit to the max size for the topology.inc file that iControl can handle?

When I try to pull the topology records (get_entry_list) from a 4.5.9 3-DNS which as a topology.inc file of 81KB I receive a "Internal Server Error - Status 500".

I don't see this problem when I pull the topology records from another 4.5.9 3-DNS that has a topology.inc file size of 25KB.

Thanks in advance.
