Files on CIFS share show no contents until updated

Issue

• A CIFS share is mounted from our NAS on several different Windows and RHEL clients
• A file is updated on the NAS by another system via FTP
• That file can no longer be read on some CIFS clients until the file is updated again

Output from RHEL system displaying issue

#df -h
Filesystem            Size  Used Avail Use% Mounted on
//CIFS-SERVER/share   1.2T  904G  281G  77% /mountpoint

# ls -l /mountpoint/examplefile

# cat /mountpoint/examplefile

# cksum /mountpoint/examplefile

Output from RHEL system working as expected
