Hi Shalin, 

Just to add, in the exception with 'CdcrUpdateLogSynchronizer - Caught unexpected exception'
it says it's because the SolrCore is loading. I don't know if this is down to the data being
quite large? 

Thanks, 

Daniel

Hi Shalin, 

I did try to do that but it hadn't made any difference, the remote clusters did not update.
Autocommit is already set on the remote clusters as follows:

	<autoCommit>
		<maxTime>${solr.autoCommit.maxTime:150000}</maxTime>
		<maxDocs>10000</maxDocs>
		<openSearcher>true</openSearcher>
	</autoCommit>

I can also see in the Solr admin pages, there is a warn message with CdcrUpdateLogSynchronizer
- Caught unexpected exception. That's all I can see at the moment. No errors apart from that.


Thanks, 

Daniel

If you manually issue a commit operation on the remote clusters, do you see any updates? If
yes, then you should set autoCommit on the remote clusters.
If no, then check the logs on the cluster which is receiving the indexing operations and see
if there are any errors.
