Hi Marco,
we tested this but the problem stays the same. We have been able to capture this in oracle monitor in an other application (optimize = true). What we see is that there are 2 red marked statements in oracle monitor.
The second one is raisign the ora-24909 Call in progress error. The statement prior to this one displays in oracle monitor an access violation at adress 00000000 Read of adress 00000000.
The sql statement which causes the access violation is a simple one:
select subject.*, subject.rowid from subject where sub_id = :sub_id.
Does the adress 00000000 indicate that the error comes from outside our application. In other words the oracle client? Any suggestions how to tackle this?
kind regards
Ruud
