I am seeing the same issue on Ubuntu Xenial with proftpd.

I am hosting 2 fairly busy proftpd servers that handle up to 10
login/secs. My /var/log/btmp are at size 0 but the /var/log/wtmp file
are up to 83M, maybe more because I restarted the servers before finding
this ticket to take a look at those.

The result is that the process /usr/lib/accountsservice/accounts-daemon
eats one full CPU core at all time.

  Nothing. Using my netbook as usual. Did not really notice when this started since earlier today did not feel any significant slowdowns.

  
  That's what happened:
    PID   USER      PR  NI  VIRT  RES   SHR   S  %CPU %MEM    TIME+  COMMAND

  accounts-daemon is using lots o CPU cycles and memory. 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.
