Jan Stránský proposed the following answer:
Hi Joe,

> Why did the stress get so large? The strain seems stable.

The strain reaches the value -0.0004 (relatively high value) in four time steps. I guess the particles have no time to move, but are pushed together by the peridoci cell producing these stress values.
To help you more, a complete code would be needed.
If not only Yade is involved, you can leave an issue on the coupling project page [1] not to pollute Yade questions

cheers
Jan
