Large core file produced by mib2agt SNMP subagent

[ITeam]

Hi.

A customer is experiencing the following problem on an L class (9000/800/L3000-7x)running HPUX 11.00:

The root file system has filled up twice during the past month due to a 108Mb+ core dump. When I check the core file the following is shown ...

bandm
B.11.00
9000/800
792947685
mib2agt
UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU

I need to know what is the cause for this. I have checked on the web for clues but have not found anything helpful thus far. Any help is greatly appreciated!

Thanks,

Hi are you using public or private snmp
if you are not using snmp you can deactivate or stop the process and also you can change to private if you are using any software like dp or openview

Hi,

I'm really shure, that this was a patch-related issue - the mib2agent had a memory leak, if I remember correctly.
The version HP-UX 11.0 is out-of-support - but patch PHSS_27858 seems to be online anyway.

Shalom,

1) HP-UX 11.00 is out of support, so I doubt anyone at HP is going to analyze your crash dump
2) Take a shot at fully patching your system, especially your SNMP solution.
3) Consider an upgrade to a supported OS such as 11.11

>When I check the core file the following is shown ...

This is NOT how to analyze a core file. You use file(1) and then gdb on it.

>I need to know what is the cause for this.

You need to get a stack trace from the core file:
$ gdb path-to/mib2agt core
(gdb) bt
(gdb) q

>The root file system has filled up twice during the past month

You could just create a directory called "core" and just live with it.

That's what the patch PHSS_27858 says. Though a 108 Mb core file seems a little too small for out of space. But that would depend on a trivial maxdsiz.

In view of the fact it's and old o/s revision; patches will be brought up to date and the situation subsequently reviewed. Thanks to all.
