Error message in syslog

On hpux 11.0 I get this error message:

vmunix: GOT INVALID CASE

Does anyone know what this means?

Just attach the syslog file or just post the exact error messages.

Thanks

Tore,

Never seen that one! Could you post the five lines before and after that message? It could be related to something else.

I just did a

strings -a /stand/vmunix | grep -i "got invalid case"

and It is in vmunix. Very interesting. Too bad it's not open source!

What were you doing when it happened?
Can you post the syslog entries surrounding the error, or better still the syslog?

Regards,

Dave.

I am going to presume you have Fibre Channel installed and in use on your system, as this is where this message appears to come from.
It is something that can be ignored, unless it becomes an issue filing up syslog, or you have system failures.
This could be caused by an application using the FC, or you may have a piece of FC hardware that is just about heading towards a failure.
I would suggest a check up on the health of the FC cards/cables etc, just to be on the side of caution.

If this continues to worry you, log a call with your local HP RC.

I agree with Melvyn that it appears to be fibre channel related. What was the last patch bundle you installed, and have you used the custom patch manager to determine if you need any other patches related to fibre IO?

Thanks for the help, I will assign points later.. How do you know its related to fiber channel? Do you know what the error message indicate? Too bad the kernel error messages is not documented.
