Could you please advice on how to fix out problem Sadly, there is no way to fix the problem with the released version. The 'repair' option will fix it most of the time, but it may happen that the database get corrupted beyond repair. The coming release is suppose to fix this problem. Basically, in all the released versions we weren't guaranteeing operations atomicity: when you do a add/delete/modify, many BTree get updated. In some cases, we may end in a situation where some of those BTrees get updated, but other not, leaving the database in a bad state. We have added a transaction support around operations that is expecting to either commit the whole modifications in one shot, or rollback it. I do expect to have it released in the coming weeks. In the mean time, the only solution is to export the data and reimport them. I'm sorry for that. During last week we have experienced a following problem: 1. When searching for uid we get an answer that uid doesn't exist, but when we try to create a uid with the same number the answer is the uid already exists. 2. We have an alarming error message in log WARN [pool-5-thread-4] org.apache.directory.server.ldap.LdapProtocolHandler.exceptionCaught():236 - Unexpected exception forcing session to close: sending disconnect notice to client. java.lang.Error: ERR_554 double get for block 134,207 at jdbm.recman.RecordFile.get(RecordFile.java:185) at jdbm.recman.PhysicalRowIdManager.allocNew(PhysicalRowIdManager.java:202) at jdbm.recman.PhysicalRowIdManager.alloc(PhysicalRowIdManager.java:177) at jdbm.recman.PhysicalRowIdManager.update(PhysicalRowIdManager.java:101) at jdbm.recman.BaseRecordManager.update(BaseRecordManager.java:281) at jdbm.recman.CacheRecordManager.updateCacheEntries(CacheRecordManager.java:417) at jdbm.recman.CacheRecordManager.commit(CacheRecordManager.java:349) at org.apache.directory.server.core.partition.impl.btree.jdbm.JdbmIndex.sync(JdbmIndex.java:590) at org.apache.directory.server.core.partition.impl.btree.jdbm.JdbmPartition.sync(JdbmPartition.java:567) at org.apache.directory.server.core.partition.impl.btree.AbstractBTreePartition.modify(AbstractBTreePartition.java:1580) at org.apache.directory.server.core.partition.impl.btree.AbstractBTreePartition.modify(AbstractBTreePartition.java:1523) at org.apache.directory.server.core.shared.partition.DefaultPartitionNexus.modify(DefaultPartitionNexus.java:491) at org.apache.directory.server.core.api.interceptor.BaseInterceptor$1.modify(BaseInterceptor.java:170) at org.apache.directory.server.core.api.interceptor.BaseInterceptor.next(BaseInterceptor.java:506) at org.apache.directory.server.core.journal.JournalInterceptor.modify(JournalInterceptor.java:229) at org.apache.directory.server.core.api.interceptor.BaseInterceptor.next(BaseInterceptor.java:506) at org.apache.directory.server.core.trigger.TriggerInterceptor.modify(TriggerInterceptor.java:370) at org.apache.directory.server.core.api.interceptor.BaseInterceptor.next(BaseInterceptor.java:506) at org.apache.directory.server.core.event.EventInterceptor.modify(EventInterceptor.java:298) at org.apache.directory.server.core.api.interceptor.BaseInterceptor.next(BaseInterceptor.java:506) at org.apache.directory.server.core.subtree.SubentryInterceptor.modify(SubentryInterceptor.java:1220) at org.apache.directory.server.core.api.interceptor.BaseInterceptor.next(BaseInterceptor.java:506) at org.apache.directory.server.core.collective.CollectiveAttributeInterceptor.modify(CollectiveAttributeInterceptor.java:165) at org.apache.directory.server.core.api.interceptor.BaseInterceptor.next(BaseInterceptor.java:506) at org.apache.directory.server.core.operational.OperationalAttributeInterceptor.modify(OperationalAttributeInterceptor.java:449) at org.apache.directory.server.core.api.interceptor.BaseInterceptor.next(BaseInterceptor.java:506) at org.apache.directory.server.core.schema.SchemaInterceptor.modify(SchemaInterceptor.java:1206) at org.apache.directory.server.core.api.interceptor.BaseInterceptor.next(BaseInterceptor.java:506) at org.apache.directory.server.core.hash.ConfigurableHashingInterceptor.modify(ConfigurableHashingInterceptor.java:185) at org.apache.directory.server.core.api.interceptor.BaseInterceptor.next(BaseInterceptor.java:506) at org.apache.directory.server.core.exception.ExceptionInterceptor.modify(ExceptionInterceptor.java:252) at org.apache.directory.server.core.api.interceptor.BaseInterceptor.next(BaseInterceptor.java:506) at org.apache.directory.server.core.admin.AdministrativePointInterceptor.modify(Admi
