At some occasions when the DDP crashes, all details might not be included in the usual DDP system logs and raid card logs.
In these situations for a deeper analysis of the crash cause, we need to get a "core" file which will be located under the DDP /tmp/avfs-dbase/ folder.
You can then just download that file with programs like winscp for Windows or from the terminal for OSX and Linux with the following command: (put the accurate DDP IP address)
scp root@172.16.5.4/tmp/avfs-dbase/core ~/Desktop/
This command will download the core file from the DDP to your client machine desktop.
Before sending it to us, please zip it as the original size can be around 200/300GB.
