Have you searched the app log for OutOfMemory? That is the only way to tell if this is happening.

You say "gives the IllegalStateException error when I try to search for a records that meet a certain criteria"
What is the criteria? Does this happen every time? The second time? Sometimes?

Are you doing any locking of your own in the application? Have you left a lower level EOF object (e.g. EODatabaseContext) locked?

Well, that last bit was important to tell us.  What does the whole
exception stack trace look like?  Do you have more than one model?  Is
you JVM running out of memory?

Well, the database is running fine and I am able to query the database
via EOModeler.  The JDBC driver is installed in the application's
classpath.  I am not sure, why it works fine with the EOModeler and
gives the IllegalStateException error when I try to search for a
records that meet a certain criteria from a Direct to Web search form.

Any ideas?

Thanks

If this is the first time you've seen this error and the application
has been running fine - I'd say that the database has fallen over. If
this is the first time you've started the application (and you've never
been able to connect to the DB) - this may well be because the
WebObjects application can not find the JDBC driver that it needs.

To troubleshoot this:
See what connection string is set in the EOModel
Check that the DB is running
Check that the JDBC driver is installed somewhere in your application's
classpath

HTH,
