Bug Description
I just noticed that ~/.cache/upstart/ folder on my computer is taking up 69GB of space. Upon further investigation, I found out that mediascanner.log and unity-panel-
I'm not entirely sure if this is related to upstart as I had removed logrotate package because of a conflict.

If you had a conflict on logrotate, that suggests that you may be installing PostgreSQL packages built for a mismatching release of Ubuntu; due to a logrotate incompatibility they declare a Breaks on either old or new versions of logrotate depending on what release they're built for.

Thanks for pointing that our Colin. Unfortunately, postgresql only publish packages for LTS releases. I've installed logrotate from 12.10 and held it with dpkg. Should work fine until an official solution.

I experienced the same, logrotate is installed and not conflicting, I had to delete a file around 60Go in size, the HDD was full (4ko remaining), and this happened 2 times sofar since I installed kubuntu 13.10.
the huge file was startkde.log. Next time it happens I will post a screenshot. I'm confident, it will ;(

I just had the same problem, deleted the logfiles and noticed, that the log is running full in no time (several MB per Minute).
I opened the file and found this message over and over again:

Same in 14.04, never noticed it before on past ubuntu releases but this is first time i`m running on a small SSD where 70gb is a big deal
| ef (mike-globalfunkradio) wrote : | #14 |
So as I understand, Upstart is not at fault, and it's an application I am running, so I have left the ./config/upstart open in Nautilus, its's empty right now since deletion, will see what application initiates the problem, shabba

This isn't limited to Unity. Just found my start-kde.log had swollen to several gigabytes because of a V4L bug that VLC had been spewing out for several minutes.
Upstart needs to be more clever about repeated messages. syslog can, for example, munch quick duplicates and say "Line repeated x times"
| Jeffrey Robbins (jeffreyrobbins) wrote : | #18 |
Just chiming in that this has effected me as well. Usually get the 'disk space is low' warning, then an 'rm -rf ~/.cache/upstart' clears up the issue. This has happened multiple times. Just tried removing logrotate and reinstalled as someone recommended earlier in the thread.

confirming same issue, only thing that made it so bad was creating a autoban script for repeat offenders, in any event this is obviously a huge bug, just 'sudo rm -rf ~/.cache/upstart' and will baby sit this bad boy. Ubuntu 14.04.1 Desktop fresh install.... :(

Same here. My 120Gb SSD just filled up. Good thing I'm an advanced user and I could manage to find the offending folder. A newbie would just need to give up. The harddrive analyzer would not give any info (maybe because the disk was full).
In my case, it was unity7.log, which was about 50Gb.
Is there any way to completely stop the upstart logging? Shouldn't that be the default for regular users? This seems like a real bug.
Logrotate is installed here, and I'm running Ubuntu-14.10 (upgraded from older version for, well, close to 10 years now :-) ).

Same problem, also unity7.log is the culprit.
It is filling with:

Ok, before rebooting, I just removed the offending file. It is growing at a rate of 1Gb every 10s or so. I will try logging out and in, and see if the log is still growing continuously ...
| Leo Milano (lmilano) wrote : | #26 |
To be clear: I removed the file before rebooting, but it got regenerated and refilled at a furious pace, with the same message: _xgeWireToEvent: Unknown extension 148, this should never happen.
At that time, "top" was reporting upstart as the most process, obviously caught in an infinite loop throwing this erroor about the extension 148.
It seems like this is the bug:

And it seems that the spamming, at least, would be removed with an upgrade of libXext to 1.3.3. Or at least, it would be nice to backport the relevant patch

This is a largely misleading bug, at least as far as Unity is concerned.
The default set up is to rotate all user-session logs once every hour, with 7 previous logs saved compressed. With a normally operating desktop session, this should be more than good enough.
Where things go awry is if you get something like Xorg or an X11 client spamming the logs with messages. All application messages from programs running in the desktop session get logged to the desktop session log, generally called gnome-session-
In short, there is nothing Unity can do to reduce the amount of garbage being logged from third-party application programs. Unity has no control over what an arbitrary program outputs and does not have any access to the output streams from applications that it launches so it could add filters.
The only way to get bugs in arbitrary applications fixed is to file bugs against the broken applications explicitly. Filing a bug against the desktop shell that launches the applications will not bring much joy.
I'm marking this as invalid for Unity, since the problem does not originate in Unity nor is it possible to provide a fix in Unity for problems elsewhere. Bugs need to be filed against the individual applications causing the problem.

Hello! I'm not a Ubuntu pro user, but I'm trying to learn more and more. Yesterday, I experienced the same situation as described here.
I work with molecular dynamics simulation, specifically with a program called GROMACS. When I was trying to do a simulation, the program told me it would take about 2 days to complete (weird, because the kind of simulation I had trying usually lasts about 6 hours). It only took a little time for my hard disk free space had being completely consumed (and breaking my simulation).
When I used the Baobap to see the disk usage, it took me to this folder .cache/upstart occupying about 70GB! I deleted it, restarted the computer, and my simulation had functioned normally (it took 5 hours to complete), and I didn't have any problems with the .cache. Very strange bug!!

It might not technically be unity's fault, why is unity logging a program's output anyway?
Spotify causes a similar issue with the `unity7.log` file, if you have too many files open it fills the log with this:
```
09:57:53.201 A [file_system_
09:57:53.201 A [file_system_
09:57:53.201 A [file_system_
```
Eating away gigabytes of space per minute, wasting write cycles of my SSD.
Maybe unity can skip adding identical lines, maybe it can notify the user when a program is putting out so much errors, maybe we can just disable the log? Anything but messing up our drive.

Why not just disable this logging behaviour by default? No one knows about ~/.cache/upstart until it fills their disk and breaks their system (if they are savvy enough to find the problem log file).
The handful of power users that might occasionally need this logging behaviour can work out how to switch it on. In the mean time, not all of the users being impacted when it fills the disk will be able to work out what needs to be done about it.
This is not an Upstart issue:
- Upstart in Ubuntu provides a logrotate script that is run to compress session logs in ~/.cache/upstart/. So, by removing logrotate you have broken that facility.
- Upstart is correctly capturing the seemingly huge amount of data generated by these applications, so the problem lies with them.
However, in a sense your removing logrotate is good in that it has drawn attention to the problems with mediascanner and unity-panel-
I would encourage you to reinstall logrotate if possible.
