Support » Plugin: Duplicator - WordPress Migration & Backup Plugin » Package Build – Host Interrupt

  • Resolved imtanuki3



    I’ve been using Duplicator Lite for some time and it’s always worked flawlessly…until just recently.

    WP 5.2.2
    PHP 7.0.33

    Package build is (intermittently) blowing up with host interrupt error.

    I keep getting errors when I do the following:
    – backup older WP 4.x prod site using Duplicator (no problem)
    – install on dev site (no problem)
    – update WordPress on dev to 5.2.2, most recent version of all plugins, etc.

    But when I backup dev site using Duplicator, it bombs out with error:
    — Host Build Interrupt
    — This server cannot complete the build due to host setup constraints.
    — To get past this hosts limitation consider the options below by clicking each section.

    1. Changed Duplicator Settings
    – Backup database only, which is only 24MB.
    – zip archive format
    – dup archive format

    2. Changed WP-Config Settings
    – define(‘WP_MEMORY_LIMIT’, ‘1024M’);
    – ini_set(‘post_max_size’, 10000000);
    – ini_set(‘upload_max_filesize’, 100000000);
    – ini_set(‘max_input_time’, 100000000);
    – ini_set(‘memory_limit’,’1024M’);
    – set_time_limit(300000);

    TBH, not sure changing wp-config is a shared server environment actually does anything.

    3. Duplicator Plugin
    – I deleted and reinstalled latest version ( – this solved the problem briefly, but issue has recurred…

    4. Other Plugins
    – de-activated all plugins, including Wordfence

    5. retested Duplicator on different subdomains on same shared server:
    – prod (works fine)
    – different site (works fine)

    At my wit’s end – Duplicator has always worked without any problems – been thrashing for several days over this one…

    Hey @imtanuki3

    Do you know if your host has updated any processes on their end or if your site has grown significantly grown in size?

    If you want to submit a support ticket for this issue we can have a closer look at your setup. Please provide a link to this thread when submitting the ticket.

    Original site (prod) was approx 475MB
    Site with issue (dev) is now 515MB.

    – at one point, I was able to back up dev (515MB)
    – now I can’t even backup just the db (24MB).

    Will open a ticket.
