Subject [jira] [Commented] (DIRSERVER-1912) Shutdown process fails from a NPE in AbstractBTreePartition
Date Tue, 19 Nov 2013 17:37:23 GMT

    [ https://issues.apache.org/jira/browse/DIRSERVER-1912?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13826721#comment-13826721
] 

Mark DeBusschere commented on DIRSERVER-1912:
---------------------------------------------

I reloaded schema and initial data.  I can't recreate the situation.  I had the previous filed
bug for the failure on start maybe
related to corruption.   Hence, I don't have any additional data for a test case.

If you want we can close this for now.
