The TNS Listener intermittently dies, crashes or reports errors with these messages in the listener log file:
TNS-12582: TNS:invalid operation
TNS-12623: TNS:operation is illegal in this state
TNS-12518: TNS:listener could not hand off client connection
TNS-12547: TNS:lost contact
TNS-12560: TNS:protocol adapter error
TNS-00517: Lost contact
VMS Error: 32: broken pipe
The listener log file is found in the ora_root:[network.log] directory.
Normally, a Listener crash will not result in the production of a VMS process dump file.
If, as part of a debugging activity, the Listener process is configured to produce a process dump file (by using the command $ SET PROCESS/DUMP/ID=<VMS pid of listener>), then when the listener terminates abnormally, the tnslsnr.exe process will create a dump file called ora_root:[network.log]tnslsnr.dmp.
You can also modify the ora_network:tnslsnr.com to add the set process/dump command there
so that it is automatically enabled on each listener start.
$ set process/name="ORA_''lname'''time'"
$ set process/dump <=====add this line
To verify that your current listener process has image dump = on use this command:
$ pipe show proc/all/id=<pid of tns listener> |search sys$pipe dump
$ pipe show proc/all/id=20218ED3|search sys$pipe dump
Image Dump: on
A subsequent analysis of the tnslsnr.dmp file will show the following call stack:

You can analyze your tnslsnr.dmp file by running the script in the following note.
OpenVMS Script to Review the contents of a VMS Oracle Process DMP file <Document 557245.1>
Note that you must pass the script in note 557245.1 the name "tnslsnr.dmp", otherwise it defaults to
In several reported cases the errors occurred after a connection using ODP.NET, Oracle Data Provider for .NET applications. The problem can be experienced with other types of connections besides ODP.NET.
