Subject [jira] [Commented] (DERBY-6425) DB got corrupted during the heavy operations.
Date Mon, 15 Dec 2014 08:46:13 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6425?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14246454#comment-14246454
] 

Maciek Makowski commented on DERBY-6425:
----------------------------------------

I'm happy to report that aligning Derby page size with filesystem block size made the problem
go away -- I haven't seen any failures in the test in the last four days with the process
having been killed more than 10000 times.

I did not manage to test with write cache off.
