Hey folks,
I've been migrating an application which indexes about 15M documents from
straight-up Lucene into SolrCloud. We've set up 5 Solr instances with a 3
zookeeper ensemble using HAProxy for load balancing. The documents are
processed on a quad core machine with 6 threads and indexed into SolrCloud
through HAProxy using ConcurrentUpdateSolrServer in order to batch the updates.
The indexing box is heavily-loaded
I've been accepting the default HttpClient with 50K buffered docs and 2
threads, i.e.,
int solrMaxBufferedDocs = 50000;
int solrThreadCount = 2;
solrServer = new ConcurrentUpdateSolrServer(solrHttpIPAddress,
solrMaxBufferedDocs, solrThreadCount);
autoCommit is configured in the solrconfig as follows:
<autoCommit>
<maxTime>600000</maxTime>
<maxDocs>500000</maxDocs>
<openSearcher>false</openSearcher>
</autoCommit>
I'm getting the following errors on the client and server sides respectively:
Client side:

When I disabled autoCommit on the server side, I didn't see any errors there
but I still get the issue client-side after about 2 million documents - which
is about 45 minutes.
Has anyone seen this issue before? I couldn't find anything useful on the
usual places.
I suppose I could setup wireshark to see what is happening but I'm hoping that
someone has a better suggestion.
Thanks in advance for any help!
Best regards,
Jim Beale
