Symptoms

  • Cannot use File Manager with started cgroups service. Blank page is shown.

  • Different errors appear while opening Domains > example.com > File Manager:

    PLESK_ERROR: Internal error ;-P
    TypeError: Cannot read property 'show' of undefined
    undefined

    OR

    PLESK_ERROR: Internal error ;-P

    CONFIG_TEXT: ERR [util_exec] proc_close() failed ['/opt/psa/admin/bin/filemng' 'jdoe' 'list' 'dirs' '/var/www/vhosts/example.com/httpdocs/wp-content' '--in-blocks'] with exit code [1]
    ERR [1] '/opt/psa/admin/bin/filemng' 'jdoe' 'list' 'dirs' '/var/www/vhosts/example.com/httpdocs/wp-content' '--in-blocks' failed with code 1.

    OR

    CONFIG_TEXT: move process 7788 to cgroup for user testuser1 failed
    move_to_cgroup(): pam_open_session() failed 6: Permission denied

    OR

    CONFIG_TEXT: Unable to open the directory: Unable to find the file /var/www/vhosts/example.com/httpdocs/css at the specified location

Cause

This is Plesk bug with ID #PPPM-6057. It will be fixed in future product updates.

Resolution

As a workaround, configure systemd limits via the following steps:

  1. Connect to the server using SSH;

  2. Uncomment and set DefaultStartLimitBurst=999 in /etc/systemd/system.conf:

    Before:

    CONFIG_TEXT: ...
    [Manager]
    ...
    # DefaultStartLimitBurst=5
    ...

    After:

    CONFIG_TEXT: ...
    [Manager]
    ...
    DefaultStartLimitBurst=999
    ...

  3. Reload systemctl daemon:

    # systemctl daemon-reload

As another workaround, for each affected user create the file /etc/systemd/system/user-$userid.slice.d/51-StartLimit.conf which contains:

CONFIG_TEXT: [Unit]
StartLimitBurst=999

To determine $userid perform the following:

  1. Login to Plesk > Subscriptions > example.com and determine system user for the subscription:22.PNG

  2. Connect to the server using SSH and execute:

    # grep johndoe /etc/passwd

    The output will be like:

    CONFIG_TEXT: johndoe:x:10001:1003::/var/www/vhosts/example.com:/bin/false

    here 10001 is userid.

So, the correct path for config file should be:

CONFIG_TEXT: /etc/systemd/system/user-10001.slice.d/51-StartLimit.conf

    Sadly this isn't working for me, don't know if I'm doing something wrong. Any updates on this question? Thank you very much.

    After aplying latest plesk updates and rebooting the system, the trouble has gone. I undid the workaround changes, rebooted again and it's still working ok.

    We've had to uninstall CGroups extension, no need to reboot and all errors gone.
