Out of memory error connecting to SFTP on IBM zOS

2004-10-04 14:22

I'm attempting to use WinSCP to connect to an IBM mainframe computer running zOS. Using Putty or sftp, I can connect without problem, but we wanted to have a GUI interface to sftp.

When I connect using WinSCP, I get a window titled "Error", with the additional information containing either "Invalid access to memory" or "Out of memory". The directory tree is not built. We've tried this using several accounts, with the same result.

Connecting to a Linux machine works without problem, so it would appear to be related to the interaction between WinSCP and zOS.

My best estimate would be that somehow, WinSCP doesn't understand the directory format that is being sent back to it, possibly getting into a loop processing the result, until memory is exhausted. But this is just a guess, based on the external symptoms.

Log follows:

Any help would be appreciated. Thanks in advance.

A little more information: While SFTP doesn't work, SCP does.

Also enable SFTP protocol logging by importing following registry settings:

REGEDIT4 

[HKEY_CURRENT_USER\Software\Martin Prikryl\WinSCP 2\Configuration\Logging] 
"LogProtocol"=dword:00000001

Then generate the same log as you have done in your post. It should include SFTP packet dumps.

BTW: Can I have a test account of your system?

I tested the version you referenced in the e-mail, and it does work. I've also forwarded the link to several others here, to give it a more complete test. If we find anything wrong, I'll let you know, but at this point, it looks good.

Thanks. :D
