When doing an Excel export with a data grid of 25K rows with a CLOB datatype. I generate the following error on demand:
The exception unknown software exception (0x0eefade) occurred in the application at location 0x77e4bef7.
The error is caused by exporting large amount of clob data which runs out of memory.
The workaround is setting the Range option to export fewer rows at a time.
Waiting for fix in a future version of SQL Navigator for Oracle.
