    [ https://issues.apache.org/jira/browse/DIRSERVER-2172?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15734943#comment-15734943
] 

Emmanuel Lecharny commented on DIRSERVER-2172:
----------------------------------------------

I'm trully sorry :/ In this case, there is no other solution (atm) than restarting the server
witha cleared database, and reinject a backup...
We are working on a replacement from the broken backend, but it takes time...

> We have upgraded apacheds from 2.0.0-M23 assuming that will fix the issue with data getting
corrupt but we are still facing the same issue.The apacheds server keeps running but data
does not load fully from front end like 400 users instead of actual 3000+ users.
> -> As a workaround we take backup of partition daily and when the issue occurs we
replace the partition from backed-up partition and restart the server.
> -> From apacheds.log we get below error trace-
