I think so. Without xrootd.async off, RTMIN+29 still shows up: [root@cmsio4 ~]# grep async.off /etc/xrootd/xrootd-clustered.cfg #xrootd.async off [root@cmsio4 ~]# printf "$(cat /var/log/messages | sed 's#%#%%#g')\n" | grep RTMIN | tail -2 Jan 21 20:31:55 cmsio4 systemd[1]: [log in to unmask]: main process exited, code=killed, status=63/RTMIN+29 Jan 21 20:53:08 cmsio4 systemd[1]: [log in to unmask]: main process exited, code=killed, status=63/RTMIN+29 On the other hand, with xrootd.async off, RTMIN+29 does not show up anymore: [root@cmsio7 ~]# grep async.off /etc/xrootd/xrootd-clustered.cfg xrootd.async off [root@cmsio7 ~]# printf "$(cat /var/log/messages | sed 's#%#%%#g')\n" | grep RTMIN | tail -2 Jan 20 19:09:48 cmsio7 systemd[1]: Received SIGRTMIN+21 from PID 296 (plymouthd). -- You are receiving this because you commented.
