Unable to distribute to peer named xxxxxx at uri=xxxxxxxx:8089 using the uri-scheme=https because peer has status=2. Verify uri-scheme, connectivity to the search peer, that the search peer is up, and that an adequate level of system resources are available. See the Troubleshooting Manual for more information
First try whether the connectivity between the search head and indexer is active. You can test it by
telnet index_ip 8089
If it is talking two way, then it might me the system resources issue.
