Snapshot cause server not reachable problem

In Our Setup, we got an alert stating "VM Server is not reachable",

While analyzing this, we found that there is no space available on the host. When we move to different datastores, the issue resolved and server is reachable.  Snapshot also cause the same problem.

How to avoid this kind of errors in future  and also suggest an easy way to find and stop snapshots

To avoid this you have two choices:

1. delete snapshot (VMware recommends preserve a snapshot for only 24-72 hours)

2. move the VM to a datastore with sufficient space to support the growth of snapshot

When you create a snapshot from a VM, a delta disk is created and over the time this disk can have to the same size as the original base disk, and this explain why you running out of space and datastore and why the VM stop to respond.

Check this KB article for some best practices about snapshots: Best practices for virtual machine snapshots in the VMware environment (1025279)
