Hi! On Centos-7: $ cat /etc/centos-release CentOS Linux release 7.8.2003 (Core) Was running du to examine the sizes of my backups and found du hung, running "ps -eLf /mnt/backup/backups" shows this: # ps -eLf | grep du root 1185 1 1185 0 1 May01 ? 00:00:00 /usr/bin/abrt-watch-log -F Backtrace /var/log/Xorg.0.log -- /usr/bin/abrt-dump-xorg -xD root 1281 1 1281 0 1 May01 ? 00:00:01 /usr/bin/abrt-watch-log -F BUG: WARNING: at WARNING: CPU: INFO: possible recursive locking detected ernel BUG at list_del corruption list_add corruption do_IRQ: stack overflow: ear stack overflow (cur: eneral protection fault nable to handle kernel ouble fault: RTNL: assertion failed eek! page_mapcount(page) went negative! adness at NETDEV WATCHDOG ysctl table check failed : nobody cared IRQ handler type mismatch Kernel panic - not syncing: Machine Check Exception: Machine check events logged divide error: bounds: coprocessor segment overrun: invalid TSS: segment not present: invalid opcode: alignment check: stack segment: fpu exception: simd exception: iret exception: /var/log/messages -- /usr/bin/abrt-dump-oops -xtD root 11090 1 11090 11 1 15:08 pts/1 00:01:10 du -s /mnt/backup/backups even after killing the du. there were two DUs shown, I killed the parent (presumably the one I started) but the one that remains seems to be un-killable.
