Failed to create a ProcessSingleton for your profile directory

  • Hello.
    I receive this error when i run opera.

    $ opera
    [2775:2775:0826/084701.022745:ERROR:sandbox_linux.cc(368)] InitializeSandbox() called with multiple threads in process gpu-process.
    [2749:2749:0826/084701.115866:ERROR:process_singleton_posix.cc(281)] Failed to create /home/login/.config/opera/SingletonLock: Operation not supported (95)
    [2749:2749:0826/084701.115984:ERROR:chrome_browser_main.cc(2140)] Failed to create a ProcessSingleton for your profile directory. This means that running multiple instances would start multiple browser processes rather than opening a new window in the existing process. Aborting now to avoid profile corruption.

    Is it possible to overcome this?

    $ opera --version
    62.0.3331.116
    $ uname -r
    5.2.9-arch1-1-ARCH
    

    I have symlinked opera configs and cache folders to cifs mount point instead of home.

    $ cat /etc/fstab
    //192.168.1.1/hidden /media/smb/hidden cifs nofail,noauto,x-systemd.automount,x-systemd.requires=network-online.target,x-systemd.device-timeout=5,credentials=/etc/samba/.smbcredentials,uid=1000,gid=985,forceuid,forcegid,vers=2.0,iocharset=utf8 0 0
    
    $ ls -la ../.cache/opera
    lrwxrwxrwx 1 login users 46 Aug 26 08:47 ../.cache/opera -> /media/smb/hidden/arch_home_const/.cache/opera
    
    $ ls -la ../.config/opera
    lrwxrwxrwx 1 login users 46 Aug 26 08:47 ../.config/opera -> /media/smb/hidden/arch_home_const/.config/opera
    

    Checking for these files in working browser i found out that it makes another symlinks:

    $ ls -la opera/
    lrwxrwxrwx  1 login users      19 Aug 26 09:03  SingletonCookie -> 5384071957362275603
    lrwxrwxrwx  1 login users      17 Aug 26 09:03  SingletonLock -> fallback-os-13855
    lrwxrwxrwx  1 login users      50 Aug 26 09:03  SingletonSocket -> /tmp/.org.chromium.Chromium.r7FAHd/SingletonSocket
