I'm using Ubuntu 9.10 (consolekit - 0.3.1-0ubuntu2) and have noticed that this daemon continually sucks up more and more physical memory over time, even when the machine is not being used. It starts around 3.7MB, but then increases. After about 1-2 days it reaches 200MB, I presume it would continue indefinitely but I usually reboot at that point. I am also trying to chase down another memory issue that massively impacts performance. The box has 2GB of RAM, but something somewhere seems to be using it, but it isn't accounted for anywhere. free -m indicates that it has been used (ignoring cache and buffers of course!), as does System Monitor. But adding up all the processes' Memory (in S.M.) or all the RES/RSS in ps or top falls many hundreds of MBs short, and this gap increases. Quite quickly it gets to the point where the box is swapping constantly, when the number/type/use of apps shouldn't require anything like it. I do not have any reason to assume this is related, but mention it just in case. Last night, not long after a reboot and before going to bed: (10MB) root 891 1.0 0.4 122652 9840 ? Ssl 21:38 0:23 /usr/sbin/console-kit-daemon This morning after box being unused all last night: (100MB) root 891 2.2 5.2 221388 108180 ? Ssl Jan25 13:33 /usr/sbin/console-kit-daemon
pmap seems to indicate something weird... libraries are being mapped with 2MB chunks each with no permissions against them. colin@iluvatar:~$ sudo pmap -d 891 891: /usr/sbin/console-kit-daemon Address

Can you reproduce this with the latest release or from git? Thanks. Might be good to try to get some valgrind info too.
(In reply to comment #2) > Can you reproduce this with the latest release or from git? Thanks. Might be > good to try to get some valgrind info too. eek, a bit beyond me! I don't suppose there is a deb anywhere that I can use on Ubuntu 0910 64bit? Compiling from source is only going to get me in trouble!
Hello?? I have downloaded the latest source, but can't even work out how to compile it and there are no instructions. Doesn't seem to be the usual ./configure ,,, make ... make install process....
seriously, I need help here!

Forget it.... its perfectly clear from all your other tickets that this is your modus operandi, its a shame such a great project has such an unresponsive, discourtious dev involved.
I'm running Ubuntu 9.10 x64 with consolekit 0.3.1-0ubuntu2. This workstation has been setting idle fresh from a reboot without logging in for the past two days, and I appear to be suffering from the same issue as this bug report describes. 18:21:05 up 2 days, 2:54, 4 users, load average: 1.07, 1.52, 1.75 Mem: 2056992k total, 1989884k used, 67108k free, 94448k buffers Swap: 6024332k total, 78180k used, 5946152k free, 300644k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1192 root 20 0 753m 558m 1932 S 10 27.8 248:28.92 console-kit-dae My pmap looks very similar, only larger numbers. I am familiar with valgrind, but I haven't dug into how consolekit works. If someone could give me some quick guidance on how to profile consolekit. I'll have 20 or 30 minutes tomorrow evening to try to dig into why this is happening.
At least one memory leak is easy to reproduce by running a loop like ssh-copy-id localhost while true; do ssh localhost true; done and watching console-kit-daemon’s resident memory usage go up by tens of kilobytes per second in `top`. (I’m running consolekit 0.4.1-4 on Ubuntu maverick amd64.)
Created attachment 37533 [details] [review] patches for a few bad memory leaks These three patches fix most of the really bad (per-session) memory leaks I found with valgrind. (Apply with `git am`.) There is still one worrisome leak within dbus-glib that might or might not be ConsoleKit’s fault: ==4766== 2,400 bytes in 150 blocks are definitely lost in loss record 997 of 1,005 ==4766== at 0x4C284A8: malloc (vg_replace_malloc.c:236) ==4766== by 0x6282514: g_malloc (gmem.c:134) ==4766== by 0x6297749: g_slice_alloc (gslice.c:836) ==4766== by 0x6298F62: g_slist_append (gslist.c:229) ==4766== by 0x4E394C1: dbus_g_connection_register_g_object (dbus-gobject.c:2373) ==4766== by 0x40F127: register_session (ck-session.c:147) ==4766== by 0x40F577: ck_session_new_with_parameters (ck-session.c:1249) ==4766== by 0x408FC7: collect_parameters_cb (ck-manager.c:1621) ==4766== by 0x40DF4F: job_completed (ck-session-leader.c:390) ==4766== by 0x59EB69D: g_closure_invoke (gclosure.c:766) ==4766== by 0x5A02DA8: signal_emit_unlocked_R (gsignal.c:3252) ==4766== by 0x5A04525: g_signal_emit_valist (gsignal.c:2983) But at least it’s much smaller than the ones I fixed.
Review of attachment 37533 [details] [review]: Thanks for tracking these down! The review tool doesn't cope very well with having two different patches for the same file apparently so I'm not sure this review will look as intended. Apart from the unref issues I mentioned this looks good. ::: src/ck-manager.c @@ +1256,1 @@ } This isn't right.

> This isn't right. Functions shouldn't generally unref passed in parameters as > a side effect. I’m pretty sure I needed to do it that way, because ck_session_leader_collect_parameters stashes the callback and the leader away in the pending_jobs queue rather than running the callback immediately. With your modified version of my patch that you committed, is there anything to prevent the leader from being freed while the job is still in the queue?
(In reply to comment #11) > your modified version of my patch that you committed, is there anything to > prevent the leader from being freed while the job is still in the queue? The hash table holds a ref. So I don't think it should happen.
(In reply to comment #12) > The hash table holds a ref. So I don't think it should happen. But still, what stops the hash table entry from being removed while the job is still in the queue?
Quite frankly, the patch look like it makes a whole lot of sense. Meanwhile, users see their servers die or hang because the daemon eats memory like crazy. Please either apply the patch, or find some other way to stop the leak. Thank you.
(In reply to comment #14) > Please either apply the patch, or find some other way to stop the leak. William already applied a modified version of my patch for 0.4.2. The leak should already be gone. http://cgit.freedesktop.org/ConsoleKit/commit/?id=7b9212fa6aff55420c58f2cacd0a941762920337 In the discussion that followed, I was just worried that his modifications introduced a potential use-after-free crash, because the JobData created by ck_session_leader_collect_parameters isn’t holding a reference to its leader. If there is no way for a CkSessionLeader to be freed with entries remaining in its pending_jobs queue (previously this was prevented by the missing unref in create_session_for_sender), then that isn’t a concern and this can be closed. Otherwise, perhaps this presentation makes it clearer why the extra ref and unref are okay? --- a/src/ck-session-leader.c +++ b/src/ck-session-leader.c @@ -409,6 +409,7 @@ job_completed (CkJob *job, static void job_data_free (JobData *data) { + g_object_unref (data->leader); g_free (data); } @@ -428,7 +429,7 @@ ck_session_leader_collect_parameters (CkSessionLeader *session_leader, ret = FALSE; data = g_new0 (JobData, 1); - data->leader = session_leader; + data->leader = g_object_ref (session_leader); data->done_cb = done_cb; data->user_data = user_data; data->context = context;

Or even just a reason that a CkSessionLeader can’t be freed with entries remaining in its pending_jobs queue, and hence the patch wouldn’t be necessary?
