Hi,
Is it your production filer ?
Please upgrade your ONTAP from Release Candidate to GA (General Availability).
What is MGWD ?
MGWD is Management GateWay Daemon (MGWD): It is the gateway into managing a cluster. It is responsible for maintaining and reporting cluster health/quorum; receiving SSH logins, SNMP, and NetApp Manageability SDK calls from management software. It does a lot, hence if ONTAP is under sustained heavy load, it may cause ONTAP to restart 'mgwd' in order to recover services and management capabilities. It ususally re-starts itself and this is an expected behavior but if it is repeating frequently, then you must raise a ticket with NetApp. However, ensure that you are on a GA first.
There can be number of reasons for mgwd to exit:
Heavy load or a bug : High usage of management processses along with heaving load from ONTAP ZAPI to the Cluster_mgmt LIF can cause this, but there can be other reasons too (bug or wahtever). Contacting NetApp helps.
Remedy is to : Move the cluster_mgmt_LIF to a different node (less busy in terms of cpu/memory usage) and observe if you are still getting those errors. It dosen't matter whether switched or switchless, you should try to move the Cluster_mgmt lif to partner node.
You haven't mentioned the FILER Model, hence difficult to assess how much memory or cores it has.
If you raise a ticket with NetApp, most likely you will be asked to move to GA release, but raise a ticket if you aren't sure how to go about it.
Thanks!
