Too many processes and unfinished

[igorkasyanchuk]

Hi there,

I have an issue: PDF generation stopped working. I see many processes related to chromium and node.

Do you have any recommendations on what I can do?

 def pdf(input_html)
    Grover.new(input_html, **{
      landscape: options[:page_orientation].to_sym == :landscape,
      format: options[:page_format].to_sym,
      prefer_css_page_size: true,
      emulate_media: "screen",
      wait_until: [ "domcontentloaded", "networkidle0" ],
      launch_args: [ "--font-render-hinting=full", "--disable-setuid-sandbox", "--disable-gpu" ],
      cache: false,
      # timeout: 0,
      # launch_args: ['--font-render-hinting=medium', '--no-sandbox'],
      print_background: true,
      scale: options[:zoom_level],
      display_header_footer: true,
      footer_template: hide_page_numbers? ? nil : footer_template,
      margin: {
        top:    "0.2in",
        right:  "0.2in",
        bottom: hide_page_numbers? ? "0.2in" : "0.45in",
        left:   "0.2in"
      },
      # debug: {
      #   headless: false,  # Default true. When set to false, the Chromium browser will be displayed
      #   devtools: true    # Default false. When set to true, the browser devtools will be displayed.
      # },
      timeout: 20_000,
      convert_timeout: 20_000,
      viewport: {
        width: 1920,
        height: 1920
      }
    }.compact_blank).to_pdf
  end

and config

Grover.configure do |config|
  config.options = {
    # format: 'A4',
    # margin: {
    #   top: '0px',
    #   bottom: '0cm'
    # },

    emulate_media: "screen",
    bypass_csp: true,

    # launch_args: [ "--font-render-hinting=medium", "--disable-setuid-sandbox" ],

    # },
    cache: true,
    timeout: 0, # Timeout in ms. A value of `0` means 'no timeout'
    request_timeout: 20_000, # Timeout when fetching the content (overloads the `timeout` option)
    convert_timeout: 20_000, # Timeout when converting the content (overloads the `timeout` option, only applies to PDF conversion)
    launch_args: [ "--font-render-hinting=full", "--disable-gpu" ],
    wait_until: [ "domcontentloaded", "networkidle0" ]
    # `    debug: {
    #       headless: false,  # Default true. When set to false, the Chromium browser will be displayed
    #       devtools: true    # Default false. When set to true, the browser devtools will be displayed.
    #     }
  }
end

Grover.configure do |config|
  config.node_env_vars = { "LD_PRELOAD" => "" }
end

Your first screenshot shows a bunch of crashed chrome processes. Your best bet would be to take a look in the Chrome crash logs to see if that gives you any hints.

I suspect the remainder of the logs you presented from the second screenshot are simply the result of the crashes. It seems like your host machine has run out of some critical resources. If it was working, but now isn't, and based on the error messages you've provided, it seems likely you've hit a process and/or file descriptor limit (be sure to check the soft and hard limits).

there were no crashes, on a fresh env if I start PDF generation I see "crashpad" and "chromium defunct" processes, and PDF was generated.
