Subject Re: Problem Updating Stats
Date Wed, 16 Mar 2016 17:47:46 GMT
It seems from the attached logs that you have upgraded phoenix to 4.7
version and now you are using old client to connect with it.
"Update statistics" command and guideposts will not work with old client
after upgradation to 4.7, you need to use the new client for such
operations.
