Sampo Saarela commented on CONNECTORS-588:
------------------------------------------
I have observed this behavior with different JVM 1.6 versions but the specific
version I'm reproducing this now is:
java -version
java version "1.6.0_34"
Java(TM) SE Runtime Environment (build 1.6.0_34-b04)
Java HotSpot(TM) 64-Bit Server VM (build 20.9-b04, mixed mode)
And javac:
/usr/java/latest/bin/javac -version
javac 1.6.0_34
Also the Solr I'm running currently is lates 4.00 from Apache site and the
ManifoldQParser is the latest from ManifoldCF home site.
I'm attaching the thread dump and SolrConfig to the original issue.
> ManifoldCFQParser dead locking Solr Core loading.

> Key: CONNECTORS-588
> URL: https://issues.apache.org/jira/browse/CONNECTORS-588
> Project: ManifoldCF
> Issue Type: Bug
> Components: Solr-4.x-component
> Affects Versions: ManifoldCF 1.0.1
> Environment: Solr 4.0 or Solr 4.0 BETA, ManifoldCF 1.0.1
> Reporter: Sampo Saarela
>
> The exact requirements to reproduce the bug are not really clear but at least
> these are required:
> Some data in the Solr index with access tokens set. Seems easier to reproduce
> with at least 1000 documents in the index.
> Solr QueryParser enabled.
> Default warm up queries enabled in the SolrConfig.xml
> At the Solr Core loading when it tries to perform the warm up queries the
> loading dead locks.
> After this Solr is in dead lock and the admin interface is locked also.
> This can be worked around by enabling ColdStart from SolrConfig so the core
> does not try to warm itself up before all the init is done in the
> ManifoldCFQParser.
