Follow-up... Issue 2 looks similar to: 6830187 False message when saving a Excel 2003 file. This resulted in a message of the form, "The file 'filename.xls' may have been changed by another user since you last saved it" even though it had only been opened by a single user. This was fixed a while ago but I don't know the release/build number.

Issue 1 is almost certainly due to something external to the 7410; perhaps client-side caching, edge-caching, proxy-caching or WAN accelerator. Issue 2: I recall an issue from a while ago related to a file having been changed by another user. I'll see if I can dig up some information on that. Again, this could be be caused by a WAN accelerator because they play tricks with time stamps and locks to reduce over-the-wire traffic. Are you using any client/proxy/edge caching or a WAN accelerator product?

File access problems like this are not related to NTP or DNS, and definitely not to Samba bugs (there's no Samba code in the 7110). This looks like an open mode conflict against an existing or previous open. Does this happen after a file has been opened by multiple users or when a single user is re-opening a file shortly after closing it? I'm running 2010.02.09.2.0,1-1.17 and I haven't heard of any similar issues - it might be worth considering an upgrade. If these issues persist, I'd recommend opening a support case with Oracle.
