Delay when saving a document in CIFS folder

[unknown-user]

With Alfresco 1.3.0 on Windows XP SP2, I have access to the Alfresco repository through CIFS, and am able to read, create, rename files sucessfully.
But editing a file, and saving it causes an idle period of about 90 secs. During this period, the explorer.exe process is frozen and nothing seems to move (nearly no CPU consumption).
Finally, the save operation ends succesfully.

Strangely, this happens only when editing files on CIFS folders on the same machine the Alfresco server runs on. When accessing CIFS folders remotely, everything works fine.

nbtstat -n gives :

Local Area Connection:
Node IpAddress: [0.0.0.0] Scope Id: []

    No names in cache

Wireless Network Connection:
Node IpAddress: [192.168.1.8] Scope Id: []

                NetBIOS Local Name Table

       Name               Type         Status

I adapted file-servers.xml to my network

<broadcast>255.255.255.0</broadcast>‍

and tried changing this element

<Win32NetBIOS api="netbios"/>‍

without success.

Any idea of a possible cause of the problem ?

Hi Denis,

Do you have an anit-virus app running on the system ?.

I've seen problems like this with AVG Anti-virus, although it only seemed to occur when accessing executable files.

Cheers

I have closed all other applications such as anti-virus or even google desktop, but the problem is still present.

I forgot to mention that I did add the registry entry SMBDeviceEnabled=0 to avoid multiple login prompts.

I now disabled all network connections other than main LAN connection.
And I did the same test with the 1.4 preview release (alfresco-1.4.ODF-Build54), to take profit of latests fixes (such as Jira AR-444).
But the problem is still present.

The console lists a lot of errors such as :

Any other idea ?

OK, you were right !

I did double-check my anti-virus settings (BitDefender 9, standard edition).
The "Quit" action on BitDefender console does not shutdown all anti-virus processes. You need to use "Disable virus shield" to completely disable it.

And then, CIFS access works fine !

Many thanks for your help,

Denis
