8212zl : Software exception in ISR at btmDmaApi.c:378
Hi
Yesterday, I had a problem with a switch 8212zl. MM1 reset at 14h25 and MM2 became active. At 18h25, switch reload and MM1 became active. For this error, I have this error :
VIT-SERV-R253# sh boot-history
Mgmt Module 1 -- Saved Crash Information (most recent first):

Hi,
What is your actual firmware version ?
Do you have a 'show log -r -a' output to take a llok to the events during the issue ?

Re: 8212zl : Software exception in ISR at btmDmaApi.c:378
Hi,
It miss some logs before the first failover to have a better understanding of the situation :
W 08/18/11 18:45:19 00268 system: xM1: Mgmt Module 1 - Failover occured E 08/18/11 18:45:12 02648 srcip: AM2: SYSLOG - failure to send out pkt
The syslog failure message do not give us much explanations about the behaviour.
We can see "many" run to start backup after the initial failover and until the normal situation.
I 08/18/11 18:45:20 02617 mgr: AM1: Startup configuration changed. New seq. number 123
I 08/18/11 18:45:49 02612 mgr: AM1: chassis subsystem saved the whole running config to startup config.

I 08/18/11 18:53:39 02617 mgr: AM1: Startup configuration changed by SNMP. New seq. number 126
There are some events that need to be analyze.
W 08/18/11 18:47:21 00374 chassis: AM1: Fabric Event F0: SLOT A NCI #7 - NCI-A:INT1 0x08000800 W 08/18/11 18:47:19 00374 chassis: AM1: Slot D: Lost Communications detected - Source Message System(40) I 08/18/11 18:47:19 00076 ports: AM1: port A7 in Trk2 is now on-line I 08/18/11 18:47:19 00435 ports: AM1: port A7 is Blocked by STP I 08/18/11 18:47:18 00435 ports: AM1: port A7 is Blocked by LACP I 08/18/11 18:47:18 00832 udld: AM1: Link state on port 'A7' is changed to 'up' state.

One suggestion regarding this events
W 08/19/11 10:21:55 00236 snmp: AM1: SNMP Security access violation from 10.1.210.2
You should modify the SNMP credential used to contact your device or remove snmp polling from this end-node.
At that time i can't further help you, it should be intersting to open a case. If you have events logging to an external server, maybe snmp traps, syslogs or radius/tacacs accounting could help us to clarify this situation.
Bye.
