I'm working on NFS server with 5 ova's inside creating the OVA provider shows 5 as expected.
But when the provider exist and adding more ova files to the NFS server the provider freezes and getting this error in the OVA pod:
Error processing OVF from OVA: unexpected EOF

Note: Deleting the provider and re-adding it when the copying complete solve the issue 
 

CNV: 4.18.6
OCP: 4.18
MTV: 2.9.0 - forklift-fbc-prod-v418:on-pr-e97186b9254c1432ca274681037b3643312888df

Always

1. mount the NFS server to my local pc storage     
****:/srv/www/html/v2v-image/mtv/ameen 
2. Create OVA provider to that end point 
****:/srv/www/html/v2v-image/mtv/ameen 
3. copy from local pc storage OVA file to ..../mtv/ameen

OVA provider Inventory doesn't reload
From the OVA pod:
"Error processing OVF from OVA: unexpected EOF"
Error from the Inventory:
Error: failed to fetch VM inventory: failed to parse provider inventory response: unexpected end of JSON input

Nothing
