too much cargo?

Is it possible to have too much cargo? what I mean is of one type as I have experienced in past space games and other games (elite II and first encounters as well as some others) where you can have too much of one type of cargo?.

Currently I get about 500 pods a session and I’m drifting around the 9500 mark (I got about 7000 before completing the game), and I have all types of cargo and at least a hundred of each type.

Essentially what I want to know is if I get too much will the game not be able to handle sat 2000 pods of sewage and crash?

On a side but related note can you have too many credits in the future trader mod? (I found a nice little earner which nets me costs me 600 creds but gives 8000 creds per sale)
