CIFS limitation?

[greglenain]

When I try to copy a set of files (49 docs, 15 Mo) through CIFS, Alfresco closes the port and raises the following exception:

Winsock rx2 len=49
10:24:32,210 ERROR [alfresco.smb.protocol] Closing session due to exception
org.alfresco.filesys.netbios.win32.WinsockNetBIOSException: null - Message too long
  at org.alfresco.filesys.smb.server.win32.WinsockNetBIOSPacketHandler.readPacket(WinsockNetBIOSPacketHandler.java:138)
        at org.alfresco.filesys.smb.server.SMBSrvSession.runSMBSrvSession.java:1511)
        at java.lang.Thread.run(Thread.java:595)

Only 20% of the files are processed before the problem occurs.

I operate that copy from a Window OS to an Alfresco 1.4 repository.

Are there some limitations in the CIFS usage ?

Thanks.

Hi,

Could you give us some more details on your OS version/service pack and network setup.

Cheers

Client side:

OS: Windows XP, SP2
IP conf: DHCP

Repo side:

Alfresco 1.4 CE
OS: Windows 2000, SP4
HTTP Srv: Apache Tomcat 5.5.12
Java: Sun 1.5.0 05
IP conf: DHCP

Network:

LAN: 100Mb
Domain server: Linux Red Hat 4

Furthermore, the copy process succeeds when using FTP instead of CIFS.

No news is good news ?

Thanks.

you are picking up 19 docs and dropping them in a cifs projection? can you identify that its the number of docs or one of the docs in particular?

[greglenain]

In that example, I've picked up 49 docs from a local filesystem and dropped them in a CIFS directory bound to my client files explorer.
And "only 20% of the files were processed".

Neither 49 nor 20% are magic numbers.

Sometimes, Alfresco may copy up to 30%, maybe 40% of the files.
But other times, the repo can't climb further than 15%.
And I can see no huge (or corrupted or evil) file hidden among the others.

Let's sum up: opposite to FTP, CIFS seems not to be able to stand the load.

Can users rely on CIFS ?

The reliability of this interface is hugely important to me.  Is there a response on this?

Hi;
We have the same message in our alfresco logfiles when cifs crashes.
Is there any progress on this?

[esanamr]

We have the same problem.

If you solve it, please tell us.

Thanks in advance

Hi,

We're trying to get hold of a packet trace from a site that has this problem as we're not able to reproduce the problem.

If you want to send an Ethereal packet trace to me it might help speed up sorting out a fix.

Cheers
