I was reading this thread, running out of disk space on /root directory, and decided to check my usage. The space on / had decreased by 3.1G from earlier in the day. I tracked the increased usage down to core dumps in /var/lib/systemd/coredump. The dumps had the forms:
#core.drkonqi.1000.6c37bee16f1b4378aeac7d4131839649.30565.1502811870000000959ab06f96905c24 and #core.single.1000.8887f571c24d4fe6b1bbe377321c92ec.10048.1502902588000000.xz
I deleted them all and recovered the lost space on /. The dumps dated from yesterday and today. From the zypper history I see that systemd was patched this morning and on the 5th. There’s an earlier version of systemd available. I’m extremely reluctant to mess with systemd. Any suggestions?
