Howcompliant is Alfresco's CIFS implementation ?

[alci]

Hi,

I'm having troubles with Cifs access to Alfresco using Linux 2.6.17 / Samba 3.0.22. Drive mounts ok, but browsing to certain directory suddenly result in a lot of network traffic and a repeated error on the client's console :

[17187997.646436] CIFS VFS: No response for cmd 50 mid 127

going over and over.

My first idea was to post on Samba's cifs linux client mailing list. They suggested running the smbtorture test suite (this test suite is designed to provide netbench fonctionnality with a small infrastracture) against Alfresco, and also dumping network traffic with Wireshark (aka Ethereal).

Smbtorture results in a lot of failed tests, but I am not a SMB protocol expert, nor really able to understand Wireshark's output.

So here is my question :
- do others encounter similar problems with Alfresco CIFS / Linux ?
- how compliant is Alfresco CIFS implementation supposed to be ?
- would anyone be interested in the smbtorture test results I got ?
- would anyone be able to help me with my tcpdump ?

Here is an example of failed tests (first 3 ones) :

A little more information on the subject : when this intense network activity occures, I get an exception on Alfresco's side :

Does this help to track down thecause ?
