Re: [CentOS] abrt-watch-log -F BUG: WARNING: at WARNING: CPU: INFO: possible recursive locking detected
Please, do not be scared from that ugly command line. It is a perfectly valid command line where abrt-watch-log process is searching for the strange strings in /var/log/messages and calling /usr/bin/abrt-dump-oops if the tool finds a string present in the list of searched strings. You can get the list of searched strings by issuing the following command: $ abrt-dump-oops -m In the upstream, we have replaced abrt-watch-log abrt-dump-oops with a single tool watching systemd-journal and the searched strings are no longer passed through command line arguments. Regards, Jakub PS: It's better to do something late, than to never do it at all.
