what is vmunix: DM_ENGINE_BO: PN_GET failed

[nomisual]

Hi,

And idea where are those error messages coming from? I keep seeing them in my syslog.log. I am running HP11i.

Thanks

I checked all of the HP-UX 11i kernel source code and didn't see any reference to these functions or printf's.

If I had to guess, some application is trying to resolve a pathname component (pn_resolve) and failing. Also, the fact that a chown(1) command is failing with "resolve_path failed" tells me that some application is trying to resolve a pathname component for a file/directory and failing.

What 3rd party applications are running on this system? Any "ps -ef" output returning a program called "engine" or "dm"?

Thanks for the quick response.

I did a search of dm or pn but the closest one that I got is:

/usr/dmi/bin/dmisp
/var/dmi/bin/hpuxci
/var/dmi/bin/swci
/usr/sbin/stm/uut/bin/tools/monitor/dm_TL_adapter
/usr/sbin/stm/uut/bin/tools/monitor/dm_core_hw
/usr/sbin/stm/uut/bin/tools/monitor/dm_stape
/usr/sbin/stm/uut/bin/tools/monitor/dm_memory

I have also attahed the entire output of ps -ef just in case.

How often are these entries being logged? If they are frequently logged then you could try stopping some of the potentially suspicious applications and see if the logging messages go away.

These could be from the stm tools, but if that were the case I would have thought one of the printfs would have shown up in my source code search.

I hate to say this, but unless someone else recognizes these messages (I didn't see them in google, news, groups, etc.) you might be down to a process of elimination - i.e. stop an application and see if the logging messages continue.

Since I cannot find a reference to these messages in the HP-UX knowledge databases, I'm guessing they are generated by a 3rd party tool, so you might want to begin with some of those, like:

patrol3.5
/usr/contrib/sbin/prngd /var/run/egd-pool
uxwdog
etc.

Good luck, and if you are able to identify the application generating these messages I'd be curious to know which one it was.

Regards,

Dave

Dave,

Thanks for your info. It was from a NAI product called Entercept. I disabled it and those error messages disappeared.

Thanks a lot for your help.
