Here are a couple of possibilities from Oracle Support Forums:
From: Oracle, Helen Schoone 06-Jan-00 17:05 Subject: Re : hostdef extension doesn't exist.
Hi. ORA-1041 is usually generated after the termination of the communications connection between a client process and the database which is usually preceeded by ORA-3113: End of file on communications channel. As mentioned in prior responses, these errors are after effects of the original problem which terminated the connection. This is often caused by an unhandled exception (ORA-7445 - core dump) in the server process or by networking problems. There can be other causes, however which would be specific to the application.
If there are no errors in the alert.log or trace files in the user_dump_dest directory, then it would appear to be related either to a networking problem or perhaps something specific to the ODBC connection. You should check the networking logs for any information, and, if errors are found, I recommend you post to the Oracle Networking forum with that information. Otherwise, I recommend posting to the ODBC forum as they may be able to identify potential causes of this error using the ODBC driver or assist with further diagnostics.

Subject: DESCRIPTION OF ORA-01041
Type: PROBLEM
Status: PUBLISHED
Content Type: TEXT/PLAIN
Creation Date: 11-MAY-1998
Last Revision Date: 27-MAY-1999
Language: USAENG
Problem Description:
You receive the error:
ORA-01041 : internal error. hostdef extension doesn't exist.
What does it actually mean?
What is the hostdef extension?
Problem Explanation:
The hostdef extension refers to the structures used to maintain the client/server communication channel.
Search Words:
hostdef extension explanation
Solution Description:
The hostdef extension referred to is a structure which was added to the control structure for the client/server communication.
It is accessed via a pointer in the original structure. When the communication between the client and the server goes awry, this can result in ORA-1041 and ORA-3113 errors.
The ORA-1041 is flagged when the POINTER to the EXTENSION structure for the HOST DEFinition (for the communication channel between the client and the server) has been nulled. This can occur when the connection gets lost 'for some reason' and hence the procedure to investigate is the same as for ORA-3113. .
