Here is a simple tool which I used to reproduce this problem. You can use it 
with the following command:

sbt/sbt run --batches 10 --inserts 100 --length 10 --parallelism 3 --host 
127.0.0.1 --trials 2

params are:
- batches - the number of batches in a single trial
- inserts - the number of inserts in a single batch
- length - the number of 3-byte characters in each text field
...

 Minor issue since doesn't really affect anything, but the error makes it look 
 like somethings wrong.  Seen on 2.1 branch 
 (1b21aef8152d96a180e75f2fcc5afad9ded6c595), not sure how far back (may be 
 post 2.1.2).
