Exception occurred org.apache.lucene.store.LockObtainFailedException: Lock obtain timed out

Hello.

I'm migrating my java application using modeshape 2.8 to modeshape 3.7.1.Final . My application is using javax.jcr.RepositoryFactory to load modeshape repository. After I changed my xml modeshape configuration to json modeshape configuration and infinispan xml configuration, I'm using oracle DB for infinispan. I tried to deploy my application. It deployed without errors, but when I tried to create a folder it said that it doesn't recognize "cf" prefix. I figured, that it happened, because I forgot to add nodetypes, that the application is using, to my configuration. After I added .cnd file to the configuration I got the following error, that I couldn't figure out how to fix.

ERROR [org.hibernate.search.exception.impl.LogErrorHandler] (Hibernate Search: Index updates queue processor for index nodeinfo-1) HSEARCH000058: Exception occurred org.apache.lucene.store.LockObtainFailedException: Lock obtain timed out: SimpleFSLock@target\content\index\nodeinfo\write.lock

Primary Failure:

    Entity org.modeshape.jcr.query.lucene.basic.NodeInfo  Id a7ca237317f1e7/jcr:system/jcr:nodeTypes/{http????www.<mywebsite>.com}Folder/{http????www.<mywebsite>.com}LastUpdateUser/String/1  Work Type  org.hibernate.search.backend.UpdateLuceneWork

Subsequent failures:

    Entity org.modeshape.jcr.query.lucene.basic.NodeInfo  Id a7ca237317f1e7/jcr:system/jcr:nodeTypes/{http????www.<mywebsite>.com}File/{http????www.<mywebsite>.com}SystemFileType/String/1  Work Type  org.hibernate.search.backend.UpdateLuceneWork

    Entity org.modeshape.jcr.query.lucene.basic.NodeInfo  Id a7ca237317f1e7/jcr:system/jcr:nodeTypes/{http????www.<mywebsite>.com}Folder/{http????www.<mywebsite>.com}CreationDate/Date/1  Work Type  org.hibernate.search.backend.UpdateLuceneWork

     ...

Then it lists all my other custom node properties with the same message. I attached part of log about modeshape.

Is this a known issue? Do you know where I should look?

Thanks,

Alexey

The error indicates that Lucene can't update the indexes because it cannot obtain a  write lock. What OS are you running on ?  (Windows, for example, is notoriously bad at handling file locks)

Looking at your configuration, one thing that comes to mind that you can try is changing from "lockingStrategy":"simple" to "auto" or "native" and see if that solves the problem.

I'm using Windows 7 Professional.

I'll try changing locking strategy and post the results.

Edit: I changed to lockingStrategy to native and this error dissapered. I still have some issues, but I'm sure they're unrelated to this question. Thanks.
