Logcheck, running on a machine with up-to-date debian unstable, sent me the following in an email yesterday. (Times and machine name removed from beginning of each line.)
upowerd[7393]: energy 99.900000 bigger than full 91.652700 kernel: [345764.796963] xfce4-notifyd[2202]: segfault at 9 ip 00007fcfb6a5c8ba sp 00007ffe9f35d320 error 4+in libc-2.26.so (deleted)[7fcfb69df000+1ad000] systemd[2055]: xfce4-notifyd.service: Main process exited, code=killed, status=11/SEGV systemd[2055]: xfce4-notifyd.service: Failed with result 'signal'. 1. Does the upowerd message indicate that something is wrong? 2. Is the simultaneous death of xfce4-notifyd a mere coincidence? (All four messages have the same time stamp down to the second.) -- Thomas E. Vaughan
