Updates and Upgrades page cannot be opened: it just loads continuously. Port 8447 is not filtered

Symptoms

  1. Tools & Settings > Updates & Upgrades (for Plesk 11 and higher) or Tools & Utilities > Updates (for Plesk 10) cannot be opened: the page just loads continuously or the following error appears in a browser:

    The connection has timed out
  2. Port 8447 is not filtered by a Firewall.

  3. Port 8447 is in listening state:

     # netstat -natp | grep :8447
    tcp 0 0 0.0.0.0:8447 0.0.0.0:* LISTEN 15357/autoinstaller
  4. After redirection from Home > Tools & Settings > Updates & Upgrades to Updates and Upgrades page it requires password for root user

Cause

The autoinstaller process is already running or hanging and the new autoinstaller process cannot re-open the port.

Autoinstaller is not terminated after closing the browser. It is still active and dies after 30 minutes of inactivity.

Resolution

For Linux:

Find and kill the hanging process manually:

# ps auxxf | grep instal
root 32351 0.0 0.0 4396 608 ? S 06:54 0:00 /bin/sh -c "/var/cache/parallels_installer/parallels_installer_Ubuntu_12.04_x86_64" "--service-mode" "--enable-xml-output" "--ssl-cert" "/opt/psa/admin/conf/httpsd.pem" "--branch" "release,stable" --web-interface --with-ssl --disable-browser
#
# kill 32351

or:

# kill `pidof autoinstaller`

Note: It is strongly recommended to check if the process is hanging and is not waiting for results from another utility. You can check activity using the strace utility:

# strace -p <PID_of_autoinstaller>

For Windows:

Kill the autoinstaller processes from the command line using the following command:

# taskkill /IM parallels_installer* /F

Note: It is strongly recommended to check the process is hanging and is not waiting for results from another utility. You can check the activity using the Microsoft Process Monitor tool .
