ORA-03137: malformed TTC packet from client rejected

[ralovets]

Hi.

We used to insert multiple rows using class Devart.Data.Oracle.OracleCommand
that called procedure from package:

my_schema.pkg_XXX.sp_insert_row(:p_1, :p_2, :p_3, :p_4, :p_5, :p_6, :p_7, :p_8, :p_9, :p_10, ..., :p_43);

after we moved to Windows Server 2019 without any code changes we started getting these errors:


ORA-03137: malformed TTC packet from client rejected: [kpoal8Check-3]
ORA-03138: Connection terminated due to security policy violation

Oracle Client 12.2.0
Devart 9.13.1098

Oracle support says issue is not on their side

if we insert just 1 row using same setup it works.

Can you help with this please?
