Necessary Virtuozzo updates have not been installed or Service Container was not upgraded after updates installation. 


To resolve the issue you should apply the latest updates for Virtuozzo 3.0.0 and to make sure that VZAgent  packages installed on Service Container have the same versions as packages on the node itself. VZAgent version should be at least 3.0.0-12.4.

WARNING: Do not upgrade Virtuozzo to the next major version (e.g. to 4.0.0), as of version 2.7, POA does not support Virtuozzo 4.0.0 yet.

Please see the following article about keeping Virtuozzo up to date:
To compare VZAgent versions installed on SVE/node use the following commands (execute on the VZ harware node):# rpm -qa | grep vzagent
# vzctl exec 1 "rpm -qa | grep vzagent"

In this examples versions do match - 3.0.0-12.5 on both Service Container and node itself.

In case the versions are different, you should update Service Container up to the current version which is installed on the hardware node. If you updated Virtuozzo using vzup2date utility, Service Container can be upgraded this way:# for i in `find /vz/vzup2date/3.0.0/ -type d -name TU* | sort -t- -k3 -n`; do vzsveupgrade -d $i; donePlease see the following article for details:
Once you have updated VZAgent, resubmit the failed task - it should complete successfully.
