We have an application that gets intermittant access violation errors
reading from an Oracle table that contains a CLOB column. If the
application runs again, with no changes, it will run to completion. The
problem is not associated with a single table. We have gotten it on
different tables. However, all of the tables we have had this problem with
have a CLOB column.
Has anyone seen this problem?
[System.AccessViolationException]: Attempted to read or write protected
memory. This is often an indication that other memory is corrupt.
