Plesk upgrade failed: "memory alloc (4 bytes) returned NULL"

Applicable to:

  • Plesk 11.x for Linux
  • Plesk 12.0 for Linux

Symptoms

  1. A Plesk upgrade fails with the following error at the bottom of /tmp/autoinstaller3.log :

    memory alloc (4 bytes) returned NULL.
    ERROR: Failed to run the Yum utility.
    The Yum utility failed to install the required packages.
  2. The following warning from the Plesk pre-upgrade checker is also present in the same log file and was displayed in the Plesk Updater web interface before the upgrade started:

    WARNING: Virtuozzo Container limit "privvmpages" was exceeded n times.
  3. The file /proc/user_beancounters has non-zero values in the last column ( failcnt ) for the limit privvmpages . This value increases after a failed upgrade attempt.

Cause

The Virtual Memory resources of the container are insufficient to run the upgrade.

Resolution

Please contact Virtuozzo Technical support to increase the exceeded memory limit on the container.
