[Touch-packages] [Bug 1316830] Re: /usr/lib/accountsservice/accounts-daemon :: memory and CPU time leak
My solotion for now based on my comment above is to modify /etc/logrotate.conf to back these files up daily with three backups and compress them. This should hold off the problem for anyone having this due to the wtmp and btmp files being large unless they have even more logins daily than I do. Be careful how you modify the cleanup of these files, the information is needed to triage intruders. -- 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.

[Touch-packages] [Bug 1316830] Re: /usr/lib/accountsservice/accounts-daemon :: memory and CPU time leak
I figured it out by attaching to the process with gdb and doing a backtrace. Apparently my wtmp and btmp files got full from devices doing remote logins on a regular basis. I became suspicious that there was something particular to what I was doing based on how few people were affected by this. Here is the size of my files: -rw-rw 1 root utmp 7160832 Nov 24 21:23 /var/log/btmp -rw-rw-r-- 1 root utmp 116148480 Nov 25 22:39 /var/log/wtmp I need to have a cleanup job for these files anyway illregardless of what the accounts-daemon does but it may help if the accounts-deamon does not process the while file if possible. I have not looked into what accounts-deamon does with the files so I am not sure if it is feasable just to look at the end of the files instead of the whole file. Even with truncating the files accounts-deamon seems to be too much of a busy body but for now at least the %CPU is below 1% on average but I do see it peak at times to 10%. The polkitd now shows up at the top more than accounts-deamon, from the threads on this I beleive that deamon is part of the same processing. -- 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.
