I've had occasional problems where I get a very quick "connection timed out" when trying to write files. Here's the symptoms:
$ tar xvf /tmp/cs854.mail.tar 2>&1 | more ./ ./1 ./.mh_sequences ./2 ./3 ./4 ./5 ... ./295 tar: ./295: Cannot close: Connection timed out ./296 tar: ./296: Cannot open: File exists ./297 tar: ./297: Cannot open: Connection timed out ./298 tar: ./298: Cannot open: Connection timed out ... etc more of the same ./606 tar: ./606: Cannot open: Connection timed out ./607 tar: ./607: Cannot open: Connection timed out tar: .: Cannot stat: Connection timed out tar: Exiting with failure status due to previous errors (The "File Exists" is partly because I tried touching 296 and 297 to see if that would avoid the connection timed out message). Several interesting aspects: (1) The scenario is utterly repeatable. It always dies on 295. (2) The "connection timed out" happens without any delay -- the timeout must be a fraction of a second (3) The FileLog for the fileserver has no relevant problems: ...

Both cases, then, happen when the file server is being asked to write many many files in quick succession.) Given that this is a repeatable problem and assuming it's a known bug, I'd be happy to run some diagnostics. If you send me email, you may get some strange messages. Despite messages about mail being rejected, I still get it, just not at the most useful place.
