[jira] [Moved] (LUCENE-5400) UAX29URLEmailTokenizer thread hangs on
getNextToken - causes cloud to stop accepting updates
[ https://issues.apache.org/jira/browse/LUCENE-5400?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Steve Rowe moved SOLR-5440 to LUCENE-5400:
------------------------------------------
Lucene Fields: New
Affects Version/s: (was: 4.5)
4.5
Key: LUCENE-5400 (was: SOLR-5440)
Project: Lucene - Core (was: Solr)
> UAX29URLEmailTokenizer thread hangs on getNextToken - causes cloud to stop accepting updates
> --------------------------------------------------------------------------------------------
>
> Key: LUCENE-5400
> URL: https://issues.apache.org/jira/browse/LUCENE-5400
> Project: Lucene - Core
> Issue Type: Bug
> Affects Versions: 4.5
> Reporter: Chris Geeringh

> This is a pretty nasty bug, and causes the cluster to stop accepting updates. I'm not sure how to consistently reproduce it but I have done so numerous times. Switching to a whitespace tokenizer improved indexing speed, and I never got the issue again.
> I'm running a 4.6 Snapshot - I had issues with deadlocks with numerous versions of Solr, and have finally narrowed down the problem to this code, which affects many/all(?) versions of Solr.
> When the thread hits this issue it uses 100% CPU, restarting the node which has the error allows indexing to continue until hit again. Here is thread dump:
