Date Tue, 08 Apr 2008 13:15:24 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2475?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12586789#action_12586789

Bassel Kh commented on DERBY-2475:
----------------------------------

I'm frequently facing this issue, most of the times; when I shutdown my server & then
start its service, the database log says (Invalid checksum), I'm working with 10.3.2.2, and
I tested it also on 10.4 (latest one), I don't have anything special to do, I'm using Hibernate
3.1.rc3, and JVM 1.6
I'm still stocking in this point waiting for somebody to help, every day we have the same
complain from our customers about the same issue.

> i tried without success but i keep testing it.
> > Can you relate the exception to any particular action that the customer
> > is taking in your application?
> till now no.
> > If it has happened multiple times, is it always the same page on
> > the same container? Or is the location different each time?
