>                 URL: https://issues.apache.org/jira/browse/SOLR-2882
>             Project: Solr
>          Issue Type: Bug
>          Components: multicore, spellchecker
>    Affects Versions: 3.4
>         Environment: WebSphere 6.1 and other
>            Reporter: Vladimir Manolov
>         Attachments: solrconfig.xml

> Currently we are experiencing a problem with Solr in combination with an active spellcheck.
> The environment that we use is a WebSphere 6.1 Application Server. We have a multi-core
configuration and we have activated a spellcheck-SearchComponent. The spellcheck-component
is an IndexBasedSpellChecker and its data is stored in a spellchecker folder.
> The problem is, that when we restart our server the application remains hanging due to
locked webcontainer-threads. When we remove the spellcheck folder and restart the application,
then the threads do not remain blocked anymore. 
> I can provide the stacktrace from the thread dump and the current solrconfig.xml
