Rick Hillegas updated DERBY-5234:
---------------------------------

    Attachment: Derby5234.java

Attaching Derby5234.java, a simpler, faster version of the repro. On my machine, this repro trips the bug in about 12 seconds. I will probably use this simpler code in the test case which will accompany the first patch.

> 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)

> Cleanup action completed
> The problem is only with INSERT statement. When i try SELECT statement on KPI.KPI_MERGEIN table it is working well.The database file system size (in seg0) is 1.3 GB
> 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 help ?
