urgent : How can i fix samba write error problem?
 

Hello. everyone.

We have implemented Digital Media solution with GPFS & linux samba & windows XP/Server.
Sometimes, we are getting a serious problem which copy files're failed when media solution try to copy & paste lots of massive files from linux samba.

When copying a massive file is failed, we can find these messages in samba log.

We thought that this problem happens whenever windows clients try to connect to samba server with both 139 port and 445 port.. so, we have configured smb.conf to enable only 445 port and also configured windows client to diable netbios over tcp/ip(139 port).

But, we couln't fix this problem..

Could you please give a great help to me ?
