Hi Sunitha, Thanks for you reply.
We tried with a new JVM and the DB was still not accessible. Unfortunately, we deleted that DB and hence, do not have log file of derby. We are using jvm ver 1.5.0_05 Currently, we are busy with a major release and hence, wouldn't find time and/or a spare machine to reproduce the problem. Will try that next week and update Derby Bug DB, with more findings. Thank you again, for responding back.

The other component retrieves these texts in chunks and process one text at a time to perform some manipulation. After fetching and processing roughly 30K texts, we get an NPE and the whole DB gets corrupt after that. We can not connect to that DB again. We use the "org.apache.derby.jdbc.EmbeddedDriver" for connecton.
