Error encountered while saving pending snapshot file

Last night I cold migrated some VMs from ESX 3.5U4 host to ESX 4 host.

Now, when I create a snapshot and have "Snapshot the virtuals machine's memory" selected, I get this error message

Error encountered while saving pending snapshot file

"/vmfs/volumes/4abae5ae-219fa-3d3-1f77-0025b2251cce/test9/test9-Snapshot1.vmsn". Reported I/O error is Generic error

When I uncheck the box to snapshot the memory it works just fine.

Any ideas?

Also to add:

When I click on the server to make a snapshot, the VM is locked and unresponsive until the the snapshot times out and throws the error message.

This behaviour of a VM becoming unresponsive for a snapshot operation when another snapshot operation is happening is expected.

Could you please confirm if you get the same error message while attempting to create a memory snapshot on all the cold migrated VMs from ESX 3.5U4 to ESX 4.

Please try the same scenario on a different VM and let us know.
