A few days ago the laptop decided to close without no relevant reason. From this day on, it randomly crashes without explanation.

This is what I (correctly?) filtered from the log files on the last crash, but I don't know what it means. At the time there are several process running: many web pages on chrome and firefox, a virtualbox machine with WindowsXP and the clamscan service.

What the root cause of the problem is? Also, do you think I have to activate the apport service in order to get more infos?

EDIT 1

While the previous contain all the logs that I thougth was relevant to the crash (inspecting the timestamps), these are the links to the full logs

The crashes occurred Nov 4 10:53:56 (actually, there was another crash about an hour earlie, but I don't know the right timestamp cause I weren't near the laptop).

Strange thing: have you noticed that there is a line with a different timestamp from the previous ones? I mean this

EDIT 2

Well, I tried again to run a clamscan, this time only inside my home directory. However, at some point, a core went over 98°C, so I stopped the process. I tried to run clamscan again in verbose mode to see if there was an error with specific files. At some point, a core temperature goes over 90°C, but this time the desktop goes off and then the computer stops. Also, I wasn't able to restart it for a while (until it is cooled down again I think). So, I think the problem is related with high cores temperature. Surely, clamscan freezes my laptop 3 times on 4 (and the only one it doesn't freeze it's because I manually force the process stop). For the previous crashes, maybe some process at a certain point starts to warm the cores; however, I don't know what process. FWIW, these are the log files filtered for the time of the event crash. syslog kern.log The strange pattern happened again. Any suggest?

  • Could you post complete content of /var/log/syslog, /var/log/kern.log and /var/log/dmesg about crash? You can add on pastebin.com and update your question with url. Usually these files are renamed during boot like /var/log/syslog.1 – Lety Nov 4 '14 at 12:24
  • @Letizia sure. Do I have to post the whole logs? – tigerjack89 Nov 4 '14 at 12:32
  • Yes, I think that could help people who want to help you :) – Lety Nov 4 '14 at 12:35
  • Hmm... could be related to this bug: bugzilla.redhat.com/show_bug.cgi?id=805285 – MadMike Nov 4 '14 at 13:45
  • @MadMike I don't know, every time the computer crashed I wasn't at the computer. Indeed, another hypotesis could be the temperature, but I don't know how to check the values (I have Psensor always running in background fwiw). Why do you think it's related to that bug? – tigerjack89 Nov 4 '14 at 14:44

Try:

$ sudo service whoopsie restart

If it doesn't work, search error with:

systemctl | grep -i whoopsie

cat /var/log/syslog | grep -i error (or failure)

and show us what's appears.

Or remove the whoopsie package completely:

$ sudo apt-get purge whoopsie

The whoopsie package will now be removed from the system.
