If I initially run a search, I get no results, but why do I get results running the same search 1 minute later?

I'm seeing the following error message, Problem replicating config (bundle) to search peer 'SPLUNKNAME:8089',Reading reply to upload: rv=-2, Receive from=https://SPLUNKNAME:8089 timed out; exceeded 60sec, as per=distsearch.conf/[replicationSettings]/sendRcvTimeout I noticed if I run a search in Splunk, I will get no event (no result) for a search, but if I run that same search again a minute later, I will get events (results) for that same search command. What is causing this? What steps should I take to troubleshoot?
