This affected me on a laptop using atop:i386 1.26-2 on Ubuntu 14.04.5 (upgraded from 12.04 I think(. I'd woken the laptop shortly before midnight, and at about 3am, the wireless connection was up but with no DNS.
$ sudo dnsmasq dnsmasq: failed to open pidfile /var/run/dnsmasq.pid: No space left on device There was 300M in /run/atop/atop.acct root 4999 1 0 981 1948 0 00:00 ? 00:01:35 /usr/bin/atop -a -w /var/log/atop/atop_20171029 600 This was in /etc/cron.d/atop # start atop daily at midnight 0 0 * * * root invoke-rc.d atop _cron So is this a packaging problem? I'd agree with urraca that /var/run (symlink to tmpfs /run) is the wrong place. How about /tmp? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1393175 Title: atop floods /run partition (causes no DNS server problem) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/atop/+bug/1393175/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
