Hi Kathi,

(I'm adding the operator (toralf.foerster) of the two relays causing the descriptor file sizes to increase)

I assume you use stem for parsing. 
What is your stem and python version?

This file just loads fine here (takes < 1minute), but I'm curious
why it contains 30311 descriptors (instead of <1000).

Amount of descriptors per fingerprint sorted by first column:

    599 D11D11877769B9E617537B4B46BFB92B443DE33D
    599 1AF72E8906E6C49481A791A6F8F84F8DFEBBB2BA

These two tor instances run on the same server with version 
and are uploading a descriptor every other minute:

Maybe we are looking at a bug here. 

@toralf foerster did you observer anything unusual in your logs?
Are your tor daemons constantly dying and restarting?
