Subject Observer went down with Read timed out exception
Date Mon, 02 Jul 2018 19:12:38 GMT
All,

I have multi data-center ldap cluster setup with other data-center with all
observers all of sudden all the observer threads went down with the
following message, any idea why they went down? We don't see any network
related issues between data-centers.
