standby ACE20-MOD-K9 reboots on its own

[Fernando Bello]

Hello Everybody,

I am experiencing the following problem:

I have 2 Cat 6509-E switches in VSS configuration with 2 ACE modules. One in each Cat6k. 

The ACE modules are running the following:

Software

  loader:    Version 12.2[120]

  system:    Version A2(3.2a) [build 3.0(0)A2(3.2a)]

We have only 2 contexts, the Admin and another one that we redirect traffic to WAAS equipment. The ANM soft running is only used for stats about the ACEs. It is version 5.2.

Since last week, the standby ACE module reboots on it own. It rebooted between 10 and 15 times until we had to leave the module PwrDown due to the constant reboots.

I tried to find any bug in the soft but I could not find anything related to that.

Had anyone has this problem? Or is aware of a bug? Or what tests should I run to discard a hardware problem/software problem?

thanks in advance for your help

Fernando

Hi all,

I forgot to say that the reason displayed in the standby ACE module for rebooting is:

last boot reason:  Service "cfgmgr"

your help will be much appreciated.

Hello Fernando,

Basically, you may need to collect a #show tech-support and also the core dumps files and open a TAC case then we can decode the core dumps to provide you with the software defect which affected you.

Here you have a link about getting the core dumps:

Hello Fernando,

Did they tell you what caused your crash?

The problem was a bug on the ACE software. We had to upgrade to A2(3.6a). It was a problem with SNMP that made reboot the module. The bug is CSCtj11617 and the ANM software version that was querying the module with SNMP messages was 5.2.

Thanks for all your help.
