Answer

To cancel a task that is stuck, please follow the steps corresponding to your environment:

Plesk for Linux

To cancel a stuck task in Plesk on a Linux Server

  1. Connect to the Plesk server via SSH.

  2. Create a backup of the Plesk database:

    # plesk db dump > /root/psa_dump.sql

  3. Find the stuck process:

    # plesk db "SELECT id,type,status,finishTime FROM longtasks WHERE status <> 'done'"

    +----+-----------------------------+---------+---------------------+
    | id | type                        | status  | finishTime          |
    +----+-----------------------------+---------+---------------------+
    | 56 | ext-wp-toolkit-task\install | started | 0000-00-00 00:00:00 |
    +----+-----------------------------+---------+---------------------+

  4. Delete the task from the longtasks table using id from step 3:

    # plesk db "DELETE FROM longtasks WHERE id=56"

  5. Delete entries from the longtaskparams table using id from step 3:

    # plesk db "DELETE FROM longtaskparams WHERE task_id=56"

  6. Kill the stuck process:

    # pkill task-async-executor

    Note: In case tasks keep getting stuck after performing the above actions, clear the lock manager using the below commands:

    # service sw-engine stop
    # rm -rf /var/lock/lmlib/container_locks
    # rm -f /usr/local/psa/var/cache/*
    # service sw-engine start

Plesk for Windows

To cancel a stuck task in Plesk on a Windows Server

  1. Connect to the Plesk server via RDP.

  2. Start a command prompt as an Administrator.

  3. Create a backup of the Plesk database:

    C:\> plesk db dump > C:\psa_dump.sql

  4. Find the stuck process:

    C:\> plesk db "SELECT id,type,status,finishTime FROM longtasks WHERE status <> 'done'"

    +----+-----------------------------+---------+---------------------+
    | id | type                        | status  | finishTime          |
    +----+-----------------------------+---------+---------------------+
    | 56 | ext-wp-toolkit-task\install | started | 0000-00-00 00:00:00 |
    +----+-----------------------------+---------+---------------------+

  5. Delete the task from the longtasks table using id from step 4:

    C:\> plesk db "DELETE FROM longtasks WHERE id=56"

  6. Delete entries from the longtaskparams table using id from step 4:

    C:\> plesk db "DELETE FROM longtaskparams WHERE task_id=56"

    This ensured I could remove the stuck task from the queue, but when I go to run the task again (ie: remove a subscription), it just gets stuck again... tried the steps to clear the lock manager, but no difference :(
