ORA-12152: TNS:unable to send break message.

[mint]

Hi,

I get the following exception during application shutdown:

ORA-12152: TNS:unable to send break message.

However, it happens only under these circumstances:

- only at the customer's site
- not directly reproducible
- session is created, used and destroyed inside of a DLL, it is private to this DLL

The exception was never reported for stand alone executables which do not use custom DLLs and have all their session access within the exe.

Call stack (created by madExcept):

Oracle RaiseOracleError
Oracle TOracleSession.LogOff
Oracle TOracleSession.SetConnected
...
System FinalizeUnits
madExcept InterceptFinalizeUnits
System @Halt0
SysInit @InitLib
UpdateLib initialization
ntdll.dll LdrShutdownProcess
kernel32.dll ExitProcess

This is with DOA 4.06 on Delphi 6 and Ora9. Any idea?

Regards

Is there a user dump trace file on the server that corresponds to this error? Maybe it contains a clue.
