Problem Description

Sessions with activated encryption can fail with an internal server error after sending or receiving a huge amount of data.
In JDBC this will happen after 128 GB, in ODBC and ADO.NET after 256 GB.
Affected are sessions using JDBC, ODBC or ADO.NET driver.

JDBC driver has to be updated to fix the error after 128 GB.
Database has to be updated to fix the problem after 256 GB.
ODBC and ADO.NET don't need an update.

Workaround

For sessions that are expected to send or receive more data you can temporarily deactivate the encryption (if allowed by database settings).
