    Default Intermittent lockups

    Not sure if this is the correct forum, but...
    Having intermittent lockups of my Leap15 x64 system. Sometimes almost daily, but generally weekly or so.
    Seems to happen after the system has been turned on for a while (>4hours), but not necessarily. I always turn off overnite.
    It 'seems' related to *maybe* Thunderbird/chrome, but again, maybe not.

    The indications are that it will start slowing down, hard drive at 100%, and I gradually lose control (in 30 or 60 seconds). If I am quick enough, I sometimes seem to be able to shutdown Chrome, and that 'can' fix it, but generally it beats me, and the only option is a force reboot.

    Link to the last 20 mins of : <journalctl --boot -1>

    Anyone have any suggestions?
    Thanks.

    Laptop or desktop?
    Which DE?
    What's the CPU load when things go wrong?
    Does the air coming out of the computer feel warm?
    Do you have a way to measure internal temperatures of CPU, GPU, motherboard?
    @desktop: Ever cleaned the air filters and the fans?
    @laptop: Ever cleaned the airways in the machine? They are blocked easily. Get a manual how to open the machine and to clean the air canals.


    When a computer stops working after a while it could be a too high temperature?
    Have installed Tumbleweed and apart from some smaller issues I like it very much.
    CPU: 8-core AMD FX-8350, GPU: GTX-760, RAM: 16GB, Disks: SSD-128GB for / (including /home), 2 times 1TB (in RAID0) HDD for Data.

    Desktop...
    KDE...
    Have tried to monitor CPU (running system activity) and has not really shown anything (or the app is not responding..)
    Vents.coolers etc are relatively clean, and haven't noticed any particular temperature issues. Have tried monitoring with 'sensors', but, again, when it starts locking up, hard to access/know if it is accurate.

    One thing I didn't mention is that the disk activity (by monitoring activity lights on the PC) is either, or close to 100%.
    Thanks.

    More definitive info would be good. Run iotop and/or iostat (you may need to install first) to gauge what is going on with disk access...
    https://www.2daygeek.com/monitor-dis...ands-on-linux/

    What do the system memory values look like?
    Code:
    free
    HDD space?
    Code:
    df -h
    HDD health? eg sda...
    Code:
    sudo smartctl -a /dev/sda | less

    You purposely have no swap?

    Your .sig stats show 8GB, but this indicates only about 6GB. If you have 4 2GB RAM sticks, one may have gone bad. Maybe reseating RAM will solve your problem.

    BTW, dropbox doesn't work for me. http://susepaste.org does, and it's accessible from your shell prompt:
    Code:
    susepaste -n hornetster -e 40320 journalctloutfile.txt

    Noticed that myself... Actually have 2x swap partitions, have remedied, to a degree.. Not sure when it disappeared, maybe the update to Leap15??

    Fingers crossed that this has benn the issue...
    Yes, had some issues with memory a while back (1x 4GB died, and had a 2GB lying around...), so now have 6GB (not optimum!)

    Note that most modern motherboards support memory in dual channel mode, meaning matching pairs of sticks in paired slots are faster. When not operating in dual channel mode, RAM speed can suffer somewhere in the neighborhood of a 40% performance loss.

    I've never tried pairing sticks of unmatched sizes in paired slots. I don't know if some of the RAM would operate in dual mode, or none, but maybe it's known to be troublesome with such a mix unless dual mode is intentionally disabled. Maybe you should try putting yours in unpaired slots if now in paired to see if it helps.
