tcp issues


Hi Guys,

I have issues with my server...I have two NIC cards on server A amd it looks like eth1 is configured...

Below is the results from server A:

ifconfig

eth1 Link encap:Ethernet HWaddr 00:50:56:86:07:91
inet addr:myipadress Bcast:172.28.255.255 Mask:255.255.0.0
inet6 addr: fe80::250:56ff:fe86:791/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:331835 errors:0 dropped:0 overruns:0 frame:0
TX packets:16852 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:21705902 (20.7 Mb) TX bytes:7523506 (7.1 Mb)
Interrupt:19 Base address:0x20a4

lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:75348 errors:0 dropped:0 overruns:0 frame:0
TX packets:75348 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:108676067 (103.6 Mb) TX bytes:108676067 (103.6 Mb)

When I transfer data from server A to server B, small files copy fine but big files like 50MB get stalled...

When i check the dmesg | grep eth

eth0: TCP Segmentation Offload (TSO) disabled by default
eth1: TCP Segmentation Offload (TSO) disabled by default
eth1: no IPv6 routers present
eth0: no IPv6 routers present
eth1: no IPv6 routers present

How can I fix this issue?

Please Help...

No errors listed. Why do you think its a tcp problem and not, say, NFS configuration?
