Hi, it looks like this is the same as reported already in OAK-8221 [0]. See my comments in that issue how to prevent and resolve this situation.
Regards Marcel [0] https://issues.apache.org/jira/browse/OAK-8221 On 09.05.19, 16:16, "zhouxu" <[email protected]> wrote: Hello expert: 1. To use Oak in my project simply add a dependency to org.apache.jackrabbit:oak-jcr:1.10.2 and to javax.jcr:jcr:2.0。 2. we construct a Repository instance,use mongodb like this: MongoClient mongoClient=getMongoClient(mongodbIP,mongodbPort,dbName,userName,password); DocumentNodeStore documentNodeStore = newMongoDocumentNodeStoreBuilder() .setMongoDB(mongoClient, dbName, 0) .setBlobStore(new FileBlobStore("D:\\amberdata FileStore")) .build(); Repository repository = new Jcr(new Oak(documentNodeStore)).createRepository(); 3.Every developer uses the oak of a local application to connect to the same mongodb, A few days later，We failed to unregister node type dw_unit_detail which we registered,it takes a long time,and throw CommitFailedException: OakMerge0004,like this: javax.jcr.InvalidItemStateException: Failed to unregister node type dw_unit_detail at
