Software forced crash on CISCO 3662 with NM-2CE1T1-PRI

Hello.

We have two devices Cisco 3662 with some NM modules installed and IOS 12.3(9d). These devices works good.

We have bought and inserted new modules NM-2CE1T1-PRI and NM-30DM. After some period of time Cisco 3662 reboots with error (Software forced crash).

After advice we have installed 128Mb RAM and IOS 12.4(10), but after 1 week 3662 it is rebooted with error again. And these devices are rebooted with error after some days to some weeks constantly.

How Can I fix this problem?

Thanks.

With regards, Sergey Bykov.

Hi ,

Below is the traceback decode.

0x60632BFC:abort(0x60632bf4)+0x8

0x606312A4:crashdump(0x60631194)+0x110

0x60657168:validblock_inline(0x60656be8)+0x580

0x60657334:validblock(0x60657318)+0x1c

0x60659A10:checkheaps_process(0x60659900)+0x110

0x6065804C:checkheaps(0x60657f74)+0xd8

I've found the culprit and it is bug :CSCdv62384 which is fixed for 7200 and it is integrated in 12.1(08)EC.

**** Good thing is open a TAC case with cisco so that they will fix it in c3660-is-mz.124-10 image.

I obserevd one more thing and it is config register value of router.Change it to 0x2102.

When router experiences software forced crash then it changes config register value also.

Hope it helps you.

Thanks,

Re: Software forced crash on CISCO 3662 with NM-2CE1T1-PRI

Hi ,

The status of the bug is closed by developer because of the following reason.

Closing this bug as with the given information we could not reach to the root cause of the problem.Put this bug in I state asking for more information.But it seems that this problem was not seen again and

hence we didn't get any response from the submitter.But since it was a valid problem(IO memory corruption) we are putting it in a C state.

**** Open a TAC case with cisco so that they can attach your case to this bug.If you know the steps to reproduce the crash then it would be helpful for developer to fix the bug.

hope it clarifies you.plz rate it.

Thanks,

satish
