One of my customer think that under his ACE, this bug id has been applied : CSCx41539.
In fact the ACE has rebooted untimely.
I would like to know which logs could prove that this bug has been involved .
this is definitely not the issue identified in ddts Cscsx41539.
What you have is a crash of the core_dump function itself. There were several ddts related to that problem.
If your customer does not run A2(1.6a) yet, I would strongly suggest to do it quickly.
