Thread: OpenSuse 12.1 freezes while copying data

  1. #1

    Question OpenSuse 12.1 freezes while copying data

    Hi,

    I have recently installed OpenSuse 12.1 on my desktop which has i5 cpu and 16 gb ram but whenever I start data copying session (using cp command or via gui) the system freezes and does not allow me to do anything. Once I go to another terminal and kill the copying session then everything becomes normal. It looks like the copying operation is eating up all memory.

    Has anyone encountered this issue and is there any fix available?

    Thanks....Ramesh Daryani

    This is of course very unusual. Many eople are doing cp commands all the time I assume.

    Is this regardless where you copy from/to? What sorts of combinations sdid you test? Is this on avery, even a small cp of a say 100 bytes file?

    Perhaps you could add some detail

    Eg: I'm copying from my /home > my USB Pen drive or

    I'm copying from my /home > my windows ntfs partition

    or whatever.....

    I am observing something very similar when copying one or more files with total of more than 1GB to an SD card:

    The info dialoge in the tray says that copying is progressing much faster than I would expect, but for the last few perecent the whole system freezes up for 30-120 minutes or so.

    "Freeze" = mouse pointer won't move; Ctrl-Alt-F1 does not respond

    Well, a few times when I actually waited, things like Ctrl-Alt-F1 still work, but take about 15minutes to show an effect. However, even once the console shows up it is not useable, since every keypress takes ages to arrive. However, if the system is left alone for an hour or so, all seems normal again and the file was copied allright on the SD card.

    I tried it a few times and waited. Even htop does not show any significant system load; besides IOwait.

    My system is openSuse 12.1 on a Dell m4500 with Intel dual-core with hypethreading (i.e. 4 cores shown by htop) and an SSD. I did the copying with Dolphin, I did not yet try the commandline's cp. The only unusual configurations I am aware of is putting /tmp, /var/tmp, /var/lock, /var/run and ~/tmp on tmpfs to ease the strain on the SSD, which is mounted with the options discard, noatime and nodiratime.

    I'm having similar issues, but mine seem to be somehow related to
    Firefox or Chrome. Any time I copy a large amount(not huge, say 350MB)
    of data to a thumb drive (gui KDE), it is sloooow, but if I have either
    of the two browsers open, the system appears to freeze, but will just be
    functioning very slowly. If I close the web browser, things go back to
    normal (more or less), although closing it takes several minutes of
    waiting. My mouse is affected intermittently. It may or may not move and
    clicks are delayed in terms of minutes.

    It is possible that Dolphin also causes similar but less noticeable
    problems.

    I did a clean install (aside from my home dir) have 4GB of ram and a
    dual core cpu, so I don't think it's a matter of having under powered
    equipment, or anything like that. I've tried the thumb drive connected
    to a port on the mobo and in a PCI usb hub, both with the same results.

    I'd love to find a solution because it really sucks not being able to
    browse while I'm copying 2GB (or more) of files that take 20-30 minutes
    anyway.

    This is not normal, but i have no idea why it could be. It people affected
    can come with a group of common circumstances, a report could be made.

    For example, are all of you using 12.1, kde, and writing to a flash device?
    Slow write is to be expected, but unresponsive system is not.

    I have experienced this when I first installed 12.1
    KDE
    Large file to Pen drive. My browser becomes unresponsive.

    But have not noticed it recently (but I upgraded kde) (and I didn't do much copying to pen drives recently)
    Let me try some tests and report back.

    Well, maybe it was something that affected kde and they corrected it. Maybe
    they tied animations to write operations, it would make sense to me.

    Hello everybody,

    I am also facing same problem as mentioned by sTurtle, but for small files less than 500Mb so there's no problem if it is more than 1GB it hangs and i have to wait untill copying is finished from one hard disk to another (locally installed) hardisk, my version is 12.1, KDE 4.7.2 , Sys.Specs.: Intel core i7-2600k, 16GB ram, 2x1TB HDD, Nvidia 560Ti, Is it due to KDE? so how can i update KDE ?

    thanks n regards
