Thread: Samba creates multiple copies of video in /tmp

  1. #1

    Default Samba creates multiple copies of video in /tmp

    I have a desktop and a laptop both running opensuse 11.2 with kde4. I have a samba share on my desktop. I tried opening a video on that share from my laptop (wirelessly) with Dolphin/SMPlayer. Here's what happened:

    The video started downloading and the system tray notified me it would take 25 minutes. I thought that was too long (video is 350MB) so I checked the download speed and it was about 2 MB/s. It didn't make sense but I let it keep going.

    25 minutes and 3.4 GB later, the download finally "finished"--according to the system tray. However, I checked my system monitor and something was still downloading at 2 MB/s. I confirmed with "df -h" that I was losing 2MB of space a second. At this point I only had about 700MB of disk space left so I rebooted (I wasn't sure how else to stop the download).

    After digging around on / I found my video at /var/tmp/kdecache-londy/krun and it was 350MB. Then I found multiple copies of the same video, of varying sizes, on /tmp/kde-londy totalling 3GB.

    I deleted the tmp files and tried it again. This time instead of clicking on the video to play it, I tried copying it to my laptop. Same thing started to happen but I didn't let it continue.

    WTF??

    Question Re: Samba creates multiple copies of video in /tmp

    For me happen the same thing. What i can see is that in the process list appear a lot of samba process even when i only clicked on a "copy" from the server. My situation is:

    Server: openSUSE 11.1 (Kde 3.5)
    Client: openSUSE 11.2 (Kde 4.2)

    Server function very good, i use it with Windows clients machines and do the job, it copy around at 6MB/s.

    In my desktop client with openSUSE 11.2 i can browse the network but when i do: left button in the file and then click 'copy' in my list process appear a lot of kdeinit4 process like:

    Any idea?? Someone can help us to debug it to give more info please...

    Thanks in advance =).

    PD: With FTP transfers from my Server pc i got transfers rate up to 12MB/s, with samba only 6MB/s in my network of 100BaseT full duplex. Why?

    Default Re: Samba creates multiple copies of video in /tmp

    I add information: when i use only Dolphin to browse the network, it start with the kdeinit4 bla bla bla process to use my network bandwidth. Only for use it.

    If i click in Dolphin to appear in first plane on the screen it fire the kdeinit4 bla bla bla process... I kill them (stop samba doesn't work)...

    ...and then double click in the folder that i want to browse and start again with the kdeinit4 bla bla bla.... kill them...

    ...and then click on the file i want to transfer and i get the kdeinit4 bla bla bla.... kill them...

    ...and then click on edit->copy and once again the kdeinit4 bla bla bla... kill them...

    ...and then i ctrl+tab to change the local folder and guess what.... doesn't appear the kdeinit4 bla bla bla ... so then pasted the file and guess again what... it start to transfer the file at a 7.5MB/s (measured acording knotify)

    ...and it finished and still i have the kdeinit4 bla bla in memory.... so i have closed dolphin and ....... cha chan.... i got new kdeinit4 samba bla bla bla process... so i have to kill them...


    HAPPY NEW YEAR FOR EVERYONE!! (and specially for those can answer this issue =P )

    I'm glad I'm not the only one with this problem.

    I found out a few more things this afternoon.

    1.) This problem doesn't affect konqueror.

    2.) After browsing to the samba share with Dolphin, the copying process (to /tmp/kde-londy) starts just by hovering my mouse over a video. I don't even have to click anything. Hovering over one video creates one copy of that file. When I first reported the problem, I had many copies because I was hovering over a bunch of video files.

    3.) Upgrading kde to the STABLE or Factory repo doesn't solve it.

    4.) "killall kio_smb" stops the downloads

    5.) I think it might be file-size related. The copying didn't start with a video of 50MB or a 100MB pdf. My videos of 350MB and over all started copying just by hovering over it.

    So, the workaround for me right now is to just use konqueror as my file browser.

    Default Re: Samba creates multiple copies of video in /tmp

    Add: I browsed with dolphin over my network and nothing happen, i double clicked on a video file, opened and watched without problem with VLC, then closed............... and it keep sending me data. =(.

    Someone know how can i debug it to offer you more info?

    Well, I don't know if we're having the same problem but my problem goes away if I remove the Information Panel in Dolphin.

    Thumbs up Re: Samba creates multiple copies of video in /tmp

    Maybe when the preview is creating, it have to transfer the whole file to do that. That could be reasonably right, but i think that it doesn't stop the transfer when change the file or the browse another folder or change windows... Maybe is the reason of transfers (copy) at 6MB/s, the another 6MB/s is used by dolphin to make the preview.

    this is quite an annoying bug. You can vote it up here:

    Glad to see others are having the same issue and it's not just me

    Having the same problem.
    Particularly bad when trying to play a video over samba share, cause the bad behaviour is the same.

    (by the way, anybody knows if with NFS there's the same problem in the same use case ?)
