NV 3430 spontaneously reboot

Hello...

Over the past two days, our NetVanta 3430 has rebooted itself. I can't seem to find the reason why. I'm receiving the following in emails from the unit:

2016.01.18 15:34:30 OPERATING_SYSTEM Cold Start

2016.01.18 15:34:31 INTERFACE_STATUS.eth 0/1 changed state to up

2016.01.18 15:34:31 INTERFACE_STATUS.eth 0/2 changed state to up


2016.01.18 15:35:40 OPERATING_SYSTEM.CORE DUMP 17.04.01.00\source\Kernel\Private\Arch\PowerPC-e500\ExceptionHandlers.cpp#239: AdFatal(DMMU: Dadr=0x005E98D4, Iadr=0x4044215C: Invalid address for read.  StackTrc:  400115E0 4044215C 404448CC 40444398 40430F44 404314E8 40431400 40430E20 40430BEC 40370770 4002034C 4001E038 400221F8 400233C0 ....Regs: r0=0x40442034 r1=0x42f89c30 r2=0x41c7cef0 r3=0x400241a0 r4=0x425e912c r5=0x00000000 r6=0x63616e63 r7=0x656c6564 r8=0x20627920 r9=0x75736572 r10=0x42f89c24 r11=0x00


2016.01.18 15:36:25 OPERATING_SYSTEM.EXCEPTION New exception reports detected.


Any help on this would be most appreciated.

Thank you!

Re: NV 3430 spontaneously reboot

You should open a ticket with Adtran support.  That is an OS exception, possibly a memory problem.  Sometimes these are caused by bugs in the software, so an OS upgrade could resolve it, but it could also be the result of hardware issues on the router.

Re: NV 3430 spontaneously reboot

We have a spare router for just such an occasion. I swapped it out.

Re: NV 3430 spontaneously reboot

It appears that you're running some really old firmware on this unit that is no longer supported. I highly recommend that you upgrade the firmware on the unit to the latest extended maintenance release R11.4.6. This will more than likely fix the issues as core dumps are usually a firmware issue.

Here is the guide for upgrading the firmware: Upgrading Firmware in AOS‌
