    On Arch x64 everything works fine with that patched package. Thanks a lot!

    @brugi: What patch? Could you share it with us, please?

    Uups, sorry. Was too fast on my last post.

    As already stated by brugi this workaround is only a half fix.

    It will work when no session is active, e.g. with sddm login manager, but NOT when a session has alreeady been started. In this case we’ll get the error from first post.

    The workaround works fine for Archlinux.

     

    Thanks a lot!

    /usr/NX/bin/nxserver –version
    NoMachine – Version 6.8.1

    Linux l 5.3.6-arch1-1-ARCH #1 SMP PREEMPT Fri Oct 11 18:28:05 UTC 2019 x86_64 GNU/Linux

    tar.gz packages are fine (at least for me)

    I’ve written a small few-liner which shows which PID has how man entries in ‘ipcs -m’

    It turns out that plasmashell is using the most resources so far

    l@l ~> ./shmleak
    #shm:353 CMD:/bin/plasmashell (pid:576)
    #shm:52 CMD:/usr/bin/x11vnc -localhost -display :0 -auth /home/l/.Xauthority -ncache_cr -noxinerama -noncache -repeat -usepw -once -nevershared (pid:4474)
    #shm:2 CMD:/usr/NX/bin/nxnode.bin (pid:881)
    #shm:1 CMD:/usr/bin/python3 /bin/onboard (pid:804)
    #shm:1 CMD:/usr/lib/kscreenlocker_greet –graceTime 5000 –ksldfd 30 (pid:18400)

     

    Thanks brotech for the time and all the kindly information and hints. I guessed that NoMachine is not the root of those problems but didn’t know how to track them down. I’ve learned much, thank you!

     

     

    For anyone who wants to use my small script:

    #!/bin/bash
    #
    # Show which Program and PID is using how much entries in kernel.shmmni
    #
    ownpid=$$
    cntpid=ipcs -m -p | awk '{print $3}' | tail -n +4 | sort -n | uniq -c | awk '{print $1"_"$2}' | sort -rn
    for p in $cntpid; do
    num=echo $p | cut -d_ -f1
    pid=echo $p | cut -d_ -f2
    cmd=ps -o command $pid | tail -n +2
    if [ ! -z “$pid” ]; then
    if [ “$ownpid” -ne “$pid” ]; then
    echo “#shm:$num CMD:$cmd (pid:$pid)”
    fi
    fi
    done

    Thanks for explanation.

    Here’s the output from ipcs -m attached

    root@l ~# ipcs -m

    —— Shared Memory Segments ——–
    key        shmid      owner      perms      bytes      nattch     status
    0x00000000 1563983872 l          777        3200       2

    0x00000000 1564049410 l          777        2048       2
    …. and 4000 more lines of this. See attachment.

     

    root@l ~# df -k /dev/shm
    Filesystem     1K-blocks  Used Available Use% Mounted on
    tmpfs            4084020 66760   4017260   2% /dev/shm

     

    root@l ~# ipcs -lm

    —— Shared Memory Limits ——–
    max number of segments = 4096
    max seg size (kbytes) = 18014398509465599
    max total shared memory (kbytes) = 18014398509481980
    min seg size (bytes) = 1

     

    Another hint, whenever this happens, VLC (VideoLANClient) fails to playback too with error:

    main error: video output creation failed
    main error: failed to create video output
    xcb_x11 error: shared memory allocation error: No space left on device

    While the same content in mplayer works.

    Now there are exactly 4096 lines output of ‘ipcs -m’ and ‘max number of segments = 4096’

    I bet it would run a little bit longe if I would increase ‘kernel.shmmni = 4096’ but this would just delay the error at all. Any idea how to identify that process that leaks shm memory? Just watch the output of ‘ipcs -m’ while running the usual apps?

    it seems that the white screen problem is related to shared memory.

    Yes, of course, but why? It worked well for more than one year but now, suddenly….
    Nothing has been changed besides updates from time to time. No new software or config changes.

    Since I’m using the enterprise client there are no logs. I there is some switch to enable client logs, please let me know. But I strongly guess that this is no client related problem because it does not work in Linux- nor Android nor Windows client.

     

    The interesting info seems to be on node/C*/session file – This was exactly the moment where it failed.

    Interestingly I downgraded to server version 4.3.23 it works again, but let me tell the full story.

    I ‘ve a Debian Wheezy 7.x (x64) Server running NX Server.

    From within the LAN (through a NAT-Router within the LAN or directly connected) I am able to connect to the Server from Windows, MAC and Android with recent client versions to NX Server version 4.3.23 (64Bit) and version 4.3.30(64Bit)

    From my Home network (NAT Router, 50MBit connection, no firewall at home, no firewall at Serverside) I am able to connect to NX Server ver. 4.3.23(64Bit) from Windows, MAC and Android recent clients

    With 4.3.30(64) I can can connect from home with Windows and MAC but not from Android.

    From Android (v 4.2.25) it is not possible to create a working connection to NX server ver. 4.3.30. (Confirmed on several Android devices).
    The connection itself works, I can see the initial remotescreen but then the client hangs, does not react to any touch gesture nor let me exit the client. While waiting for connection, which can take up to 5 minutes, sometimes it is not even possible to the Back-Key. Sometime I get a ForceClose.

     

    Where can I find client logfiles on Android or enable debug logs on Android (beside the very limited logcat output)?

    Now that I’ve a point to look further what exactly is going on I can make some tests in the next few days and provide client and server logs.
    NX 4 is exactly what I`ve looked for for many years – and know/watch for at least that 10 years . A mixture of cross platform VNC,RDP,Chrome Desktop. A product I really want to help to make it better and better.

     

    best,
    jnko
