Ubuntu crash - how to read log files
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.

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?/var/log/kern.log

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 myhome
directory. However, at some point, a core went over 98°C, so I stopped the process. I tried to runclamscan
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 Thestrange
pattern happened again. Any suggest?-
Lety over 9 yearsCould 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
-
tigerjack over 9 years@Letizia sure. Do I have to post the whole logs?
-
Lety over 9 yearsYes, I think that could help people who want to help you :)
-
tigerjack over 9 years@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?
-
Lety over 9 yearsCould you check if in /var/crash is present file created at boot time? I guess no and I agree with you that it would be better to enable whoopsie in order to get more information.
-
tigerjack over 9 years@Letizia no file at all (actually there is one file, but it is old and related to nvidia drivers, so I don't think it's related with my problem). Oh, I didn't know that now
whoopsie
manageapport
. Have you read the "strange things" in my last edit related towhoopsie
? -
Lety over 9 yearsYes, I saw, but I don't know why. Sometimes this kind of problem can due to intensive cpu usage, but I do not know so well syslogd to say whether this is the case.
-
tigerjack over 9 yearsadded further infos in EDIT 2 @Letizia and all the others obvsiouly
-
tigerjack over 9 yearscrash continues to happen even under high (even if not extremely high) temperature. The only device without a sensor temperature is the ssd; well, there is also the video card, but it was disabled. It could be possible that the ssd is the one which heats up more than the others?
-
tigerjack over 9 yearsalso, it seems that the hdd temperature is constantly above 60°C
