[0888] 29/08/2013 21:07:46 BUG7060 SWD: HARDWARE WATCHDOG INTERRUPT EVENT

Exact Root cause is unknown. It was found that semWatch feature affects system behavior - with semWatch feature enabled INI occurs after first watchdog. With semWatch disabled INI doesn't occurs (when debug shel is active).
WrapEnabled flag is used to enable this feature. It's enabled by default.


Solution

Design team has developed MPLR32939 which will prevent the continuous warm start.
Please open an SR to Avaya and request MPLR32939 (CPP4/7.6) and follow the below action plan

1) Install MPLR32939
pdt> pload
Patch filename? p32939_1.pp4
Retain patch (y/n)? [y] y
Days patch vulnerable to sysload? [3] 0
In-service initialize threshold? [5] 0
In-service days to monitor inits? [7] 0

2) On active CS, perform the following command in PDT:
taskSwitchMonStart

3) After first watchdog(if occurs) please perform the following command:
storeTaskSwitchResult

After this log file will be created.

Note that if INI/warmstart persist even after patch installation please open DBG shell (pdt> debug)
Then execute commands mentioned in steps (2) and (3) from DBG shell.
You can close DBG shell using debug end command.
Provide the logs to Avaya Support for further investigation.
