Hi Mike, hi all

I downgraded to Version 1.1.11. Whit this version I don't have the
problem any more.
So the difference must be between 1.1.* an 1.2.3.

It's not easy to build a test-case to reproduce:
I tranfer an 10 MB zip file over an 64K ISND-connection from one
SMB-Share to an other, using the SmbFile.copyto method.
The transfer most time crashes between 5 and 7 MB, but the connection is
still available.

With the 1.* version it works and the full 10 MB can be transfered.
why
