samba - Jan 2013 - NT_STATUS_NO_MEMORY when browsing file server on Belkin modem

Hello,

Can someone help me to track down the source of this problem? I'm trying 
to access a file server running on a Belkin modem with an attached USB 
drive. Judging my the quality of the firmware on the device, I'd say 
there's a good chance of it being buggy. But it works well enough on a 
Windows machine, even one running inside Virtualbox under Linux. I 
therefore see no reason why it shouldn't work using a Samba client.

When I try to connect using smbclient, I can connect OK, and put and 
retrieve files. But if I try to browse the share using 'ls' or
'du', it
returns immediately something like 'NT_STATUS_NO_MEMORY listing *' So I 
can't get a directory listing of the share, which pretty much makes it 
useless.

Interestingly, when I try to connect to it using XBMC running on my 
Apple TV, which I assume incorporates samba pretty much off the shelf, 
it also returns an error indicating problems allocating memory.

I have enough IT skills to build samba from source and try to reverse 
engineer and debug it. I'd just like to benefit from the experience of 
others before I go down that path.

Many thanks,

Jonathan

What we need are comparative network traces from accessing
the box via windows and smbclient. See
https://wiki.samba.org/index.php/Capture_Packets for info
how to do that best.

Thanks,

Thank you, that patch did the trick.

Will this patch be incorporated into future releases of samba?

Cheers,
