The only thing this server does is file-server. Not event through nfs just keep all file. All data file system is using ZFS. I got pretty big (or let's say not small) pool (150To) and the server got 48Go of Ram. Since we using zfs send/received from a another server I got daily a zfs core dump. I failed to find which process make this core-dump but it's definitvly zfs : pid 23943 (zfs), uid 0: exited on signal 6 (core dumped) pid 70462 (zfs), uid 0: exited on signal 6 (core dumped) pid 71042 (zfs), uid 0: exited on signal 6 (core dumped) I check every zfs file system and don't find any corup data. One of the zfs sender is running FreeBSD 10 the other linux/Debian. What's you advise ? Should I upgrade to FreeBSD 10. ?
