[Samba] 3.0.25b-1.1.72-1411 - copy from and to the same samba share

[Dragan Krnic]

A copy from a samba share to the same share frequently fails
with error "The specified network name is no longer available".

The remaining copy is the same size as source but corrupted.

WinXP logs an obscure NetBT Event ID 4322, which says
"NetBT could not process a request, because at least one
OutOfResources-Exception occurred in the last hour".

One can reproduce this error anytime if one chooses a big enough
file and copies it a second time before the first copy is done.
Samba 3.0.24 does not have this bug.

When a double copy fails there is this line in full_audit log
at the moment the errors pop up:

Jul 16 14:52:15 p92 smbd_audit: [2007/07/16 14:52:15, 0]
lib/util_sock.c:read_data(534)
Jul 16 14:52:15 p92 smbd_audit:   read_data: read failure for 4 bytes
to client 172.24.204.176. Error = Connection reset by peer

Is this a known problem ?
Can I produce more diagnostics to help fix it ?
