Bernd Eckenfels commented on IO-544:
------------------------------------
Ah ok, now I get it. I think I have seen this before and I do believe it is a
SMB client bug. There are some directory caches and in a single client
situation an unknown need for Cache invalidation. Maybe we can work around if
by looping a limited time (but more often than currently). Related parameters:

> Should FileUtils.copyFile be flushed and synced before comparing file sizes?

> Key: IO-544
> URL: https://issues.apache.org/jira/browse/IO-544
> Project: Commons IO
> Issue Type: Bug
> Components: Utilities
> Affects Versions: 2.5
> Environment: Win Server 2008, x86
> Reporter: Sean Poulter
>
> I've been struggling to troubleshoot intermittent {{IOExceptions}} thrown
> from {{FileUtils.doCopyFile}} when copying 2-4KB files from a local temporary
> file to a network drive. Despite the error, the file appears on the network
> drive when I check. Should the output channel/buffer be forced/flushed before
> closing, and synchronized before comparing the file lengths? It's a rather
> intermittent issue on a relatively high throughput PC so I'd expect there to
> be more IO latency than normal.
