SRC is local machine
TGT is remote host

If I copy a file in binary mode from SRC to TGT via ssh that is too large
for the filesystem on TGT, winscp crashes with Windows
"Abnormal program termination"

Version is WinSCP version 404
SRC is Windows 2003 from a Terminal Server session
TGT is HPUX 11 PA_RISC 64bit.

Session details are:
Session protocol = SSH-2
SSH implementation = OpenSSH_3.9
Encryption algorithm = aes
Compression = No
File transfer protocol = SFTP-3
------------------------------------------------------------
Server host key fingerprint
ssh-rsa 1024 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx
------------------------------------------------------------
Can change permissions = Yes
Can change owner/group = No
Can execute arbitrary command = No
Can create symlink/hardlink = Yes/No
Can lookup user groups = No
Can duplicate remote files = No
Can check available space = No
Can calculate file checksum = No
Native text (ASCII) mode transfers = No
------------------------------------------------------------
Additional information
The server does not support any SFTP extension.

Thank you for your reply.
Here is the part of the log that should be relevant.

. 2007-10-02 12:02:59.054 Fatal error while disposing the SFTP queue.

So its the server who simply kills the connection. The question is whether this behaviour of winscp is by design.
