Rick Hillegas commented on DERBY-5234:
--------------------------------------
Thanks, Mike. I will add a test case to the patch. Please add comments on top
of the patch once I've checked it in--I think that your comments will be more
useful than mine. I will also put some thought into writing a follow-on patch
containing tests for edge cases. Thanks.

> Project: Derby

> Components: Store
> Affects Versions: 10.5.3.0

> Solaris 5/10 in test environment with JDK 1.6
> Reporter: Varma R
> Priority: Critical
> Labels: ERROR, XSDG0, apache, corruption, data, derby,

> One of the derby database table "gets corrupted"/"indicates connection not
> available" during processing inserts from java client application as shown in
> the trace and the only way to recover from this error is to rebuild the DB -
> by deleting the data and creating the tables again. This happens once in a
> while (thrice in a span of two months) and the java application (run in
> multiple servers), which updates the database, processes around 100 million
> transactions per hour (in total and each transation results in 4-5 updates to
> the DB)
> There are eight tables in the derby database.

> Cleanup action completed
> The problem is only with INSERT statement. When i try SELECT statement on

> Can anyone help me out in identifying the problem that why for one table
> alone its throwing the above error message ? Would upgrade to a new version
