Mark Miller commented on SOLR-1028: ----------------------------------- Looking at the logs of the latest failure I found a bit (this is one of only 2 or 3 types of fails I've seen though) It appears that it's trying to create the index for a new collection under the existing collection1's data dir - I don't know if this is due to a race or what, but it's obviously not supposed to be happening... oasc.CoreContainer.recordAndThrow SEVERE Unable to create core: collectionLazy5 org.apache.solr.common.SolrException: Cannot create Caused by: java.io.IOException: Cannot create directory: C:\Users\JenkinsSlave\workspace\Lucene-Solr-trunk-Windows\solr\build\solr-core\test-files\solr\collection1\data\index [junit4:junit4] 2> at org.apache.lucene.store.NativeFSLock.obtain(NativeFSLockFactory.java:171) > Automatic core loading unloading for multicore > ---------------------------------------------- > > Key: SOLR-1028 > URL: https://issues.apache.org/jira/browse/SOLR-1028 > Project: Solr > Issue Type: New Feature > Components: multicore > Affects Versions: 4.0, 5.0 > Reporter: Noble Paul > Assignee: Erick Erickson > Fix For: 4.1, 5.0 > > Attachments: SOLR-1028.patch, SOLR-1028.patch, > SOLR-1028_testnoise.patch > > > usecase: I have many small cores (say one per user) on a single Solr box . > All the cores are not be always needed .
