Subject [jira] [Commented] (DERBY-6048) Derby database would not start after machine crash
Date Mon, 21 Jan 2013 04:10:13 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6048?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13558518#comment-13558518 ] 

Dag H. Wanvik commented on DERBY-6048:
--------------------------------------

You mention that this issue has been seen in three Derby versions, ( 10.8.1.2, 10.8.2.2, 10.9.1.0). Does this mean you can reproduce it?
It looks like an error during recovery which is bad. Have any of the log files been touched after the crash prior to attempting reboot?
