I work uninterruptedly for 8-10 hours a day, and every single day the system completely freezes - mouse, keyboard, music, videos and anything running stops. After a minute or 2, the system gradually returns with some intermittent breaks until normal operation is reached after about 5 minutes. An error message appears with the option of send system crash log - what I always do.

There is no apparent pattern triggering the crash. My system log before and after the crash is here. I'm not advanced user, so there isn't any identifiable clue in this log for me. Any advise will be appreciated.

System info:

  • Memory 7.7 GiB
  • Processor Intel Core i7-4500U CPU @ 1.80GHz x 4
  • Graphics Intel Haswell Mobile
  • OS type 64-bit
  • Disk 903 GB (43% used)

  • I just want to say that I see this as well on my Ubuntu server. Even cron jobs that need to run every minute simply get delayed, and after a few minutes all is well again. I am very curious if anyone can spot something wrong here. – Jos Apr 27 '17 at 22:59
  • Today, 10:30 ( another crash). The log [here](https://pastebin.ubuntu.com/24473630/), this time few lines what I think represent the log of the system crash. – Jecogeo Apr 28 '17 at 16:02
  • The crash behavior continues over and over again. Most times now, the system doesn't show any crash until I click on calendar or shutdown button in the panel. It really weird. If someone has any clue, please report. – Jecogeo Jun 17 '17 at 21:28

I had been facing this issue for a while. This could be due to the system running out of memory when there are too many processes going on. This answer might help you which talks about increasing RAM and SWAP. Increasing SWAP size worked for me as I have not experienced freezes lately. 

# sudo swapon -s
# sudo swapoff /swapfile 
# sudo fallocate -l 2G /swapfile

# sudo mkswap /swapfile
# sudo swapon /swapfile
# sudo swapon -s
