Stefan Seelmann commented on DIRSERVER-2172:
--------------------------------------------
Not much changed between M12 and M23 in this regard. ApacheDS still uses JDBM
as underlying storage which has know problems. The designated successor Mavibot
is not yet finished due to limited time and resources. Help is very welcomed.
> ApacheDS 2.0.0M12 in production, getting ERR_554 double get for block block

> Key: DIRSERVER-2172
> URL: https://issues.apache.org/jira/browse/DIRSERVER-2172
> Project: Directory ApacheDS
> Issue Type: Bug
> Components: ldap
> Environment: GNU/Linux x86_64
> Reporter: sourabh sihare
> Priority: Critical
>
> 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-
