Description
I am doing a basic stress test :
- a TestingServer that keeps restarting in one thread
- a Curator client that keeps creating/deleting a node in another
After a few seconds, ether the create or the delete fail:
Thu Oct 01 15:35:10 PDT 2015 - Node /test has successfully been removed.
Thu Oct 01 15:35:10 PDT 2015 - Recreating /test
Thu Oct 01 15:35:10 PDT 2015 - Restarting server...
Thu Oct 01 15:35:14 PDT 2015 - Restarting server...
Thu Oct 01 15:35:15 PDT 2015 - ERROR: node should be removed.
Thu Oct 01 15:35:15 PDT 2015 - Data of node is: test
Node has been mysteriously created...

The create shouldn't fail, we're within 5 seconds of the create and the connection timeout is 10 secs.
This is surprising as this basic scenario is - AFAIK - the reason Curator exists in the first place.
