Same here, this time on Debian 3.16.43-2+deb8u1 with kernel 3.16.0-4-amd64. I know this is an Ubuntu forum, but this bug ticket is the closest one for this issue that I could find. Package accountsservice has version 0.6.37-3+b1.
This machine is running ProFTPd 1.3.5 with a high number of FTP sessions. As you can see the wtmp file gets rather large: -rw------- 1 root utmp 3072 Jul 14 09:53 btmp -rw------- 1 root utmp 44259072 Jul 17 16:07 wtmp -rw------- 1 root utmp 119944320 Jul 17 07:49 wtmp.1 -rw------- 1 root utmp 120503424 Jul 16 07:35 wtmp.2 -rw------- 1 root utmp 120549888 Jul 15 07:35 wtmp.3 This is probably the reason why accounts-daemon is eating away most of by CPU: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 587 root 20 0 481984 98616 2520 R 73.5 9.6 1204:19 accounts-daemon -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to accountsservice in Ubuntu. https://bugs.launchpad.net/bugs/1316830 Title: /usr/lib/accountsservice/accounts-daemon :: memory and CPU time leak Status in accountsservice package in Ubuntu: Confirmed Bug description: netikras@netikras-netbook ~/received/accountsservice-0.6.20 $ cat /etc/lsb-release DISTRIB_ID=LinuxMint DISTRIB_RELEASE=16 DISTRIB_CODENAME=petra DISTRIB_DESCRIPTION="Linux Mint 16 Petra" uname -a Linux netikras-netbook 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:12:00 UTC 2013 i686 i686 i686 GNU/Linux Nothing.

Stats above are after restarting daemon for several times. Before this memory usage was >60%; CPU - 100%. In file attached you should be able to see there's a loop checking for something repeatedly. Not sure this is the cause though, but feels like it.. It's the first time I've noticed this problem, but I often leave my computer running unattended so I cannot tell if it's really the first time it happened.
