Dcop error on boot (Scorpion) but system works ok

Dai_trying · 2017-06-03 14:46

I have noticed about three times on my laptop when switching on I get this error dialog pop up which says...

error message wrote:

There was an error setting up inter-process communications for TDE. The message returned by the system was:
Could not read network connection list.
/home/dai/.DCOPserver_scorpionmain__0
Please check that the "dcopserver" program is running!

The system seems to be running fine and I have not noticed anything strange happening, and my network connection (wifi) is established by the end of the startup procedure.

This is not happening every time I start the machine, but it has happened three times in the last four (or five?) days. Any idea what could be causing this? like I say it doesn't seem to be affecting anything other than displaying the error before desktop starts to load.

We will check it and post back as soon as possible.

Dai_trying · 2017-06-03 15:22

Thanks guys, it doesn't appear to be affecting anything so could be like a false positive report or something.

Havent experienced that Dai but Im also running Scorpion on a desktop with ethernet connection.

Dai_trying · 2017-06-03 16:25

Yea, a strange one as it seems to be all working after desktop appears but sometimes shows the error...

q4osteam · 2017-06-03 17:45

We are not able to reproduce so far. You could try to cleanup the TDE cache, just do login to terminal console, ctrl+alt+f1, make sure you are not logged TDE in. Remove all folders 'kdecache-*' in '/var/tmp/' directory and reboot. Please, post a result back.

Dai_trying · 2017-06-03 20:44

I will do this now (when I log-out) although a quick look in /var/tmp shows only tdecache-* so should I assume they are the ones to remove?

EDIT:
I removed them as per your instructions, and rebooted and everything seems normal although I have started/shutdown the laptop about 4 times today and only had the error message happen on one occasion, also I forgot to mention (in case it is pertinent) I am using the auto-login feature too.

I will report here if the message comes back.

After you mentioned auto-login I played around with my test setup, but so far havent been able to cause the issue.

Dai_trying · 2017-06-04 17:01

I haven't had it happen again yet and I've started and shutdown this laptop three time so far today. Let's hope it was just a glitch that doesn't return

crosscourt · 2017-06-04 18:48

Im around 30 times on three different installs.

Dai_trying · 2017-06-05 11:13

Ok I got the error message again, this time I had the power adapter plugged in which I don't usually do. This is the only thing I have done differently and this is the third boot up today and the previous times no error message appeared. I will reboot the laptop a couple of times testing if power adaptor makes a difference all the time and post back with results.

EDIT:
I rebooted with power supply still attached and no error message, then removed power supply and rebooted without error message, I then powered off the machine reconnected power supply and restarted it after a few minutes and no error message... So conclusion is that may have been coincidental that power supply was attached when it last happened...

Ive tried to simulate what you did with my laptops but so far nothing.

Dai_trying · 2017-06-05 15:32

Yes I can't reproduce the error so it could be something system specific... I might try a fresh installation when I have time.

crosscourt · 2017-06-05 15:58

Thats what I was thinking as it could be specific to your hardware.

Ok, to revive an old issue!

I was running Audacity with an 8 hour audio file. Then I tried to load a 5 hour file into another copy of Audacity. Everything hung up. No display refreshes. So I did a shutdown and reboot. But, I get the same DCOP server message at boot up and cannot startx unless I do so as root. (which I currently am running under) I have tried cleaning /tmp removing all the .DCOP files and the .ICEauthority with no luck. Getting late tonight and I got a busy day tomorrow so it may be day after tomorrow (Thursday) before I get back, or I may work on it some tomorrow evening.
When I copied my FireFox files to root I did get a popup that I was running out of space. Possibly I have just exceeded what disk space I have, so I may try cleaning some non-essential files and see what happens.

Dai_trying · 2018-02-28 09:38

I still have the occasional error message when I boot up, but everything still seems to be working and nothing has stopped my desktop from showing and functioning as expected, I would suspect that hdd space could be the culprit in your case and also I would check the amount of swap space available too just in case that could be a problem.
After I get the error message I don't change anything, sometimes I might reboot just to see if it comes back (it hasn't happened after reboot as yet) but as I have had no detrimental effects I put it down to "one of those things"

JimW · 2018-02-28 22:09

Ok, I've removed over 40 Gb of data and it still gives the same error. After starting with sudo startx it comes up and says I still only have 3% free space! That was what it said before I moved the 40 Gb to USB thumb drives!
I have looked for files that Audacity may have left floating but can't find anything, even in .Audacity. Is there something I can do that would find those huge files and delete them? Since I was running 2 copies of Audacity when this happened I feel that there must be something that it caused that I need to get rid of. I have cleared /tmp so I don't think there is anything there. Possibly swap space? Any thoughts on what to do (other than never do that again!)?

Ok, back after trying a couple more things.
In /usr/tmp I found two files labeled "audacity-jim####" with the # being a bunch of numbers. I deleted those and shutdown (not restart).
Still cannot log in as user. When the login windows comes up and I enter user/password, it closes and opens a terminal window. Typing startx I get-
"Only console users are allowed to run x server"
So, I have to still use the sudo startx.

@JimW
You could try to cleanup the TDE cache, just do login to terminal console, ctrl+alt+f1, make sure you are not logged TDE in. Remove all folders 'tdecache-*' in '/var/tmp/' directory and 'tde*' in '/tmp'. Next remove directories 'cache-*' .. 'socket-*' .. 'tmp-*' in '$HOME/.trinity/' and reboot. You should also check and set ownership of all files in your home folder:
$ cd /home
$ sudo chown -R your_username:your_groupname your_home_folder

Dai_trying · 2018-02-28 23:20

@JimW
Also you could run df and see if any mounts are low on space, it might give you a clue as to which part of the system is low. After running the previous instructions from the @q4osteam of course

JimW · 2018-02-28 23:51

Thanks Q4OSteam - it looks like the removal of the 'tdecache-jim' folder cleared the problem up. Able to log on normally now - sure hated running as root!

@Dai - thanks, I'll give it a check!
