Knut Anders Hatlen commented on DERBY-2475: ------------------------------------------- You mentioned that you have tested it with Derby 10.4, but you didn't state the exact version number. A problem that could cause database corruption (DERBY-3347) was recently fixed on the 10.4 branch, so it would be interesting to know whether or not you ran your test with that fix. I think the discussion should be moved away from this bug report, as it is closed and its environment description says that it's possibly a broken hard drive, in which case it is not a Derby bug. The following open bug reports also mention invalid checksum errors, and I think it would be best to continue the discussion on one of them: DERBY-2677 DERBY-3087 DERBY-3606 DERBY-3607 DERBY-3611 > invalid checksum > ---------------- > > Key: DERBY-2475 > URL: https://issues.apache.org/jira/browse/DERBY-2475 > Project: Derby > Issue Type: Bug > Components: Store > Affects Versions: 10.2.2.0 > Environment: windows xp, notebook, possibly broken hard drive! > Reporter: Fabian Merki > Attachments: defekt2.zip > > > one of my customers gets on a notebook the following exception: > ---------------------------------------------------------------- > 2007-03-17 09:01:53.042 GMT: > Booting Derby version The Apache Software Foundation - Apache Derby - > 10.2.2.0 - (485682): instance c013800d-0111-5f21-a736-000002cd2118 > on database directory C:\Programme\merkisoft\kursverwaltung\database\kurs > Database Class Loader started - derby.database.classpath='' > ------------ BEGIN SHUTDOWN ERROR STACK ------------- > ERROR XSDG2: Invalid checksum on Page Page(28,Container(0, 1248)), > expected=3'455'715'557, on-disk version=3'357'396'866, page dump follows: Hex > dump > > hex dump => see attachment > > i'm using the embedded version together with hibernate on the notebook. > when i transfer the db to my pc and execute select * from <all tables> i get > no errors at all. > we checked the disk about 3 times (with error correction): no result and it > still happens. > when i create a new db on the notebook it happens after a while again. > the db is about 35 mb. i could put it somewhere for developers (please email > me). > > i've seen someone else having a similar problem but i couldn't find a > solution yet. > > any help is very welcome! > > ------------------ > hi bryan > thanks for the quick reply! i tried to answer your questions. i hope it > helps. > > Does this happen for this customer over and over? > > Or did it happen only once? > yes only that, but it happend 6 times. > > Is the customer able to provoke the error on demand? > 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?
