Hi to all, i'm experiencing constantly restart on 2 VPS when any long proccess, like a backup of a user with a very large amount of files, start on server.
After investigating, i've found these messages based on the null byte characters are encountered previously in /var/log/syslog and various other log files /var/log/kern.log.
Maybe it's possible that this is a hardware-level issue?
Original hardware is a Fujitsu with 2x Intel Xeon E5-2620v4, 64GB ECC DDR4 RAM, 2x 1.92TB Micron Enterprise SSD ZFS RAID 1
Actually there are on it 3 VPS with assigned only real hardware recources.
Thanks to all.
