Hello!
I' using solrj 1.4.0 with java 1.6, on two occasions when indexing
~18000 documents we got the following problem:
(trace from jconsole)
Name: pool-1-thread-1
State: WAITING on
java.util.concurrent.locks.abstractqueuedsynchronizer$conditionobj...@11

amingUpdateSolrServer.java:196)
org.apache.solr.client.solrj.request.AbstractUpdateRequest.process(Abstr
actUpdateRequest.java:105)
This is the codeblock that's used for indexing
public UpdateResponse
indexDocuments(Collection<SolrInputDocument> docs, int commitWithin){
UpdateResponse updated = null;
if(docs.isEmpty()){
return null;
}
try {
UpdateRequest req = new
UpdateRequest();
req.setCommitWithin(commitWithin);
req.add(docs);
updated =
req.process(solr);
} catch (SolrServerException e) {
logger.error("Error while
indexing documents ["+docs+"]", e);
} catch (IOException e) {
logger.error("IOException
while indexing documents ["+docs+"]",e);
}
return updated;
}
The commitWithin used in application is 10000.
If I'm not wrong it's a deadlock. Is this a known issue?
With regards
Michal Stefanczak
