>                 URL: https://issues.apache.org/jira/browse/SOLR-12832
>             Project: Solr
>          Issue Type: Bug
>      Security Level: Public(Default Security Level. Issues are Public) 
>          Components: search
>    Affects Versions: 5.5.1

> All of a sudden the solr api is going in hung mode and when we look into the reason we do see its taking up the diskspace by creating a huge java core dump file in this case its 32GB.
>  
> Here are the more details:
> Solr version : 5.5.0
> JVM: IBM Java 1.7.0
> JVM Memory setup: 40GB (total system memory is 128GB)
> This is happening occasionally and right now as a workaround we are just clearing up that huge java.core dmp file to make it work. And the major thing is that we couldn't able to open this file in any tools to see what's causing the java.core dump file.
>  
> So we really need some help here on how / where to start debugging what's the issue is?
>  
> Any basic things to be verified here in this case? please let me know as this causing a huge impact.
>  
> Thanks,
