Samba locks-up after a while

Hello Kevin,
I don't know much about suse linux or the IPChains stuff,
but you might further isolate the problem by doing the following:
When the problem occurs:
1. ps -ef|grep -i smb  to see if there are a LOT of smbd processes running
   (indicating a lot of reconnection attempts and some sort of failure)
2. netstat -an|grep 139  to see if there are a lot of netbios connections
   left hanging around in a fin_wait or other state that has used up some
   system table resource that is hanging tcpip...
Just a thought,

Subject: Samba locks-up after a while

Hello all,

I have setup a friends Samba 2.2.0 with SUSE linux 6.4 and also 
we use the linux server as a firewall using IPChains for Internet 
access (with NAT).  I have the same setup and it all works fine.

The problem he's getting is when copying large files (>100MB 
each), Windows 98 just gives the error message 'Network Error'. 
However after about 5 minutes, I don't get this problem at all. When 
this error occurs, the TCP/IP on the server also stops responding 
and hence on internet access stops. The only way to fix it is to 
reset the server or restart the Network service.  However the 
problem comes back!

I would be grateful if anyone can put some light on this or even the 
best place to start looking. The only difference between the two 
servers is that mine is a PDC and my friends is set for Workgroup.

P.S. I have also tried Samba 2.2.1 but had the same problem. I 
don't belive it is hardware, because changed all the parts and re-
install linux.
