High load average on serveral DUS7 cluster nodes

We have fixed the issues. Cluster environment is healthy. No cluster nodes are under High Load anymore. We are now checking the monitoring system and every vServers one-by-one.

Also, Virtuozzo technical support is investigating the cluster stability over the next days. We apologize for any inconveniences caused.

Most chunk serves and services are up again. Load average is now on every node back to normal. Some singular vServer might be still affected, but the overall status of the cluster looks better now.

Cluster has reached "healthy" status again, but we still see that some nodes are acting under High Load average. Therefore we are preparing to reboot several nodes one after one inside the cluster.

The cluster is now in "self-healing" mode, by moving data chunks to less used chunk servers. At the moment, we consider the cluster data replication as "degraded", but being at 93% healthy (coming from 88% about 10-15 minutes ago).

We are also checking, with the data center, if the cause can be related to attacks on the infrastructure and/or on single machines.

We see that nodes are recovering now and are coming back to a normal Load Average.

Sorry, but we are experiencing high load averages on various cluster nodes. We are looking into the issue with Virtuozzo technical support.
