New features

Configurable service restart thresholds

(CC-4100) Restart thresholds are available to manage services. In the Control Center browser interface, you can edit the service to specify a value in the new field Restart when memory usage exceeds % of requested RAM. When your threshold is reached, the service restarts automatically.

For more information about how this feature can be used, see the release notes for Resource Manager 6.2.1.

Notes and workarounds

CC-4039: rpcbind fails to start when IPv6 is disabled

Disabling IPv6 can prevent the NFS server from restarting, due to an rpcbind issue. Zenoss recommends leaving IPv6 enabled on the Control Center master host.
