If you start receiving such type of error messages on VPS then you are running short of some of resources that are allocated to your VE, you can check which resource is causing problems by running following command from shell of VE you are facing problems with or from Node.
check failcnt colum it will display number of failures due to inappropriate allocation of particular resource to VPS
you can increase particular resource by editing configuration file for particular VE, you can find configuration fle at /etc/vz/conf/VEID.conf replace VEID with actual VE ID in our case it would be 110.conf, find resurce that is having maximum of failure count increase it to some higher extent and then restart VE.
Or you can run following command to increase resource
vzctl set <VEID> --<resource name> barrier:limit --save
for eg.
vzctl set 110 --privvmpage 107150:117150 --save
