Core dump and exception report NetVanta 3430

Hi All,

     I've got a Netvanta 3430 that was running some old firmware

I had a core dump on it, but the core dump was below.

2102.01.04 16:43:55 OPERATING_SYSTEM.CORE DUMP\source\Kernel\Private\Arch\PowerPC-8260\IsrHandler.cpp#280:
AdFatal(DMMU: Dadr=0x00000010, Iadr=0x000104B8: No permission to write.  StackTrc:

r31=0x0488de98 LR=0x00010628 CTR=0x0000fe94.)

I assume the above could be fixed with a firmware upgrade, hoever the exception report it generated was not complete.

The report is long, so I won't post it here, but below is just the last part of the file.

It puts some funny characters in the exception report, and then proceeds to show me some of the unit's running config........

  permit host 172

Does anyone know if this is indicitive of a faulty unit?

Also what is the process that the unit goes through in creating an exception report? - perhaps my unit was powered off or something whilst generating the report?

Re: Core dump and exception report NetVanta 3430

Hi Matt:

These are good questions.  I wouldn't hesitate to go ahead and upgrade to the latest maintenance release, R10.9 at the time of this post.  If you notice a pattern of instability or see exception reports along with uptimes less than you expect, then it's probably time to call support and open a ticket.  If there are power issues, then the exception report could be incomplete.  I don't understand the process for exception reporting very well.  Either way, you'll probably need to open a support ticket to have the exception report analyzed.  If your 3400 series unit exhibits a pattern of trouble following the firmware update, I recommend calling in right away.
