Subject [jira] Commented: (DERBY-4075) ERROR XSDBB: Unknown page format at page Page(613,Container(0, 1024)) when running MailJdbc (Embedded) system tests
Date Wed, 25 Mar 2009 15:50:57 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4075?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12689143#action_12689143

Kristian Waagan commented on DERBY-4075:
----------------------------------------

Myrna,

 o How frequently do you see the error(s)? Is it on every run, or more like one out of every
ten?
 o If you see them frequently, can you spare a few cycles to run with the Sun VM as well?

It's hard to tell, but since you can reproduce this on two different machines and operating
systems, I'm guessing the bug is either VM or timing dependent.
The problem is that by changing VM, you are most likely affecting the timing too...

The only thing I have to offer at this point, is to keep running and restarting the test after
about 24 hours. It is correct that you have seen the error within a day, right?
If you share your latest findings, I'll configure my environment in a similar way and start
the tests again.

Hex dump:
> The error up to that point appear to me no different from other errors that this test
is expected to produce (40001, 23505, 4XL01) except that the very first error is a grant error.
> I think we can't have a release until this corruption is explained away or fixed.
