/var/log/paciagent.log on Virtualization Nodes contains the error in big amount:
2015-02-06 12:02:20,504 ERR fill_ve_states: failure PRL_ERR_INVALID_ARG @[agent.c][stat_send_thread])
SNMP service fails to respond on the Virtuozzo node.
As a workaround, restart snmpd service on the affected hardware node:
# /etc/init.d/snmpd restart Stopping snmpd: [ OK ] Starting snmpd: [ OK ]
