Invalid access to memory

2010-07-21 14:25

Hello

I have encountered an 'Invalid access to memory' error when running the sftp session.
The error is displayed on 'exit' command - see last line of the script below.
The problem is that script exists with code 12 so when I automate it, it is reported as a failure. When I check the results, all seems to be fine.

The environment is as follows:
windows 2008 64 bit
winscp 4.2.8 build 818

the executed batch file:

SETLOCAL EnableDelayedExpansion
pushd E:\BIASDW_ETL\config\brel_sftp
winscp.com /console /script=winscp_script.txt /log=sftp.log /parameter %date:-=%

the winscp_script.txt file:

option batch on
option confirm off

open sftp://xxxQ@xxx.xxx.xxx.xxx:22 -privatekey=PRIVATE.ppk -hostkey="ssh-dss 1024 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx"

cd /Usr/xxx/IN
lcd \\host01\download

get file1_%1%.csv file1.csv
get file2_%1%.csv file2.csv
get file3_%1%.csv file3.csv
get file4_%1%.csv file4.csv

close
exit

The log file:

Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

You will find my address (if you log in) in my forum profile.

I had the same error

2010-08-06 11:27

I have a Windows script that send a backup file to a remote NAS Server. This script is scheduled to execute at night.

I just upgraded the WinSCP from 4.2.7 to 4.2.8 compilation 818. I did not any other changes. This morning when I check the log files I watch the "violation memory access". However, the files were correctly sent to the NAS Server.

Environment:
Source Server.: Windows 2003 Server SE sp2 + winSCP 4.2.8
Remote Server.: FreeNAS 0.7.1 Shere.

An extract of windows script is:

The WinSCP script is:

The script ends with an errorlevel=1 due to WinSCP return code

The WinSCP log file is similar to the others:

also getting invalid memory access in script session

2010-08-13 22:19

DOS window which started the scripted session reports invalid memory access error. here is a sanitized version of the relevant portions of log file. error appears to happen when issuing the "close" command. script works fine with winscp versions 4.2.4 and 4.2.6. have not tried version 4.2.7.
