Oracle Linux 7 : ps command as root produces a WARNING

When running a “ps” command as root user on Oracle Linux 7 (and CentOS 7), you may see the following :

root       694     1  0 09:01 ?        00:00:00 /usr/bin/abrt-watch-log -F Backtrace /var/log/Xorg.0.log -- /usr/bin/abrt-dump-xorg -xD
root       692     1  0 09:01 ?        00:00:00 /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 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

Note that, at the least, we can read “ernel” where we could expect “kernel”, “eneral” instead of “general”, “nable” instead of “unable”, “ysctl” instead of “sysctl”. Not very nice.

Whether it looks like a bug, it seems not to be. Please read that interesting description Red Hat Bugzilla – Bug 976581. It’s explained the first letter is explicitly not there to be able to catch both capital/lower letter.
It’s an old bug report, a new one has also been reported more recently for CentOS 7 on CentOS bug Tracker. Minor, but it’s worth to keep an eye.
