Hi Charles,

This is likely the result of heavy load on Riak; how much have you tuned 
Riak & your OS?  Please make sure to review our tuning documentation.

Thought it's not clear in our CS documentation, make sure you have the 
leveldb backend properly tuned:
LevelDB backend: 
http://docs.basho.com/riak/latest/ops/advanced/backends/leveldb/

You might want to try increasing the request_pool and bucket_list_pool 
values in your cs app.config, making sure to keep the value of 
pb_backlog in Riak greater than the sum of the two pool values.  The 
recommended pb_backlog value is 256.
http://docs.basho.com/riakcs/latest/cookbooks/configuration/Configuring-Riak/
http://docs.basho.com/riakcs/latest/cookbooks/configuration/Configuring-Riak-CS/

If you go to http://docs.basho.com/riak/latest/ you can find an entire 
section on Tuning under "Riak for Operators" in the left navigation that 
might help you tune your cluster.

Regards,
   ~ Zack ~
