Hi,
Last night an ES40 system went down with this _panic_string :
0xfffffc0000655560 = "Processor Machine Check"
Looking in the "/var/adm/crash/crash-data.x" I saw the output below ...
It seems to be a problem with one of the CPU but after rebooting the server,
all went right without trouble ...
To my mind, it should be a problem with a corrupted memory but how can I
debug the EV6.8AL (21264B) error codes ?
Thanks in advance !
Jérôme
