   No, I have not set the watchdog-reboot to "true" yet. Even though Sun
Support
   Engineer told me try to enable this parameter to true (but he's not
sure), but 
   I am kind of hesitate to do that. Because once we enable the
"watchdog-reset", the
   system would reboot by itself whenever, for any reason, the system
detects 
   hardware errors that it can not recover. These errors could be CPU,
memory, disks, etc...
   Beside the E-cache bug, since this is a production system, I do not want
to have it 
   reboot by itself.

   What is your recommendation ?

Here it is:

Nov  7 09:20:06 cms11052 unix: panic[cpu0]/thread=0x614cd780: CPU0 Ecache
SRAM Data Parity Error: AFSR 0x00000000 00400004 AFAR 0x000001fe 01801000

  No, none hit <Stop-A>

>>Core dump is easy.  Savecore is enabled by default on sol 7 and up.
>>Previous versions, look at /etc/init.d/sysetup.

	Yes, I've done it. That's why it prevents the system from
auto-booting.

Thank you very much for your inputs.
