Single index on indexer not getting new data. Other indexes are.

[a238574]

I have a splunk cluster with 3 indexers. I have a non replicated index that for some reason has stopped getting new data on one of the indexers. Other indexes on the same node are getting data. What can I look for to figure out why this index on the one node is not getting new data. The data is coming from a pair of Heavy Forwarders which is my 1st target to check but not sure where to look.

Found my issue... the indexer in question had been moved to a new IP but the config change had not been updated on the HF

Start with error message in $SPLUNK_HOME/var/log/splunk/splunkd.log on Indexer and Heavy Forwarder. Also check whether receiving port is listening on Indexer.
