Subject [jira] [Created] (DIRSERVER-2046) Some data can be lost when using ldapadd command to insert data

linzhao created DIRSERVER-2046:
----------------------------------

             Summary: Some data can be lost when using ldapadd command to insert data
                 Key: DIRSERVER-2046
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-2046
             Project: Directory ApacheDS
          Issue Type: Bug
          Components: ldap
    Affects Versions: 2.0.0-M19
         Environment: cent OS 6.5 with openldap installed
            Reporter: linzhao


In our system, we need to do data backup and restore for apacheds. For now, we use the ldapsearch
and ldapadd command to do BR function. We use ldapsearch to backup apacheds data to be a ldif
file and use ldapadd to restore the data. But when the ldif is a little big, I always found
that the data can't be restored successfully, but the ladpadd command showed that the data
can be added successfully. No exceptions for ldapadd command. But the restored data didn't
exist in the node. This bug only happened when the ldif file is a little big. I mean if the
data entry greater than 500 entries. But the node for backup and restore is using mavibot
partition. Because I found so many problems for jdbm. So I change it to mavibot partition.
Another question is that do you know is there some good way to do the data backup and restore
for apacheds?
Below is the exceptions from apacheds when problems happened:
