M2 Autotester PUT_SUCCESS not expected

Reposting a follow up to @119 here since that post is quite old now.

When the MS2 tester sends a PUT to the correct server, PUT_SUCCESS is returned but that’s apparently an unexpected answer.

“abc” is hashed to “900150983cd24fb0d6963f7d28e17f72”, which s2-gr13-m2-server2:42607 should be responsible for.

What is the expected answer from the server be here?

Hi,

The issue can be seen in the logs. You can see from the log that the response received from the KV server is 

PUT_SUCCESS abc cde
PUT_SUCCESS abc cde

But we expect 
PUT_SUCCESS abc cde

That means you are sending the success message twice.
