Happens with all restarts with either the search head or search peer. We perform weekly restarts for maintenance purposes. I've created the distsearch.conf using both the splunk web and editing the distsearch.conf manually and everything is fine until we do a restart of splunk. For some reason it is not reestablishing that connection. This began when we upgraded the search peer (indexer) to 7.0. The search head is currently at 6.3.
