write_sock stream errors

Hello,

I'm running 2.4.31 on 2.6.7 (server and client) and the server, very
shortly after connection with the client, gives these out:

slave1 enbd-server: stream   548: <# 585> write_sock stream 0x8065734
has closed socket  
slave1 enbd-server: enbd-server   548: <#1957> talk_hello Introduction
failed: Invalid argument  
slave1 enbd-server: stream   551: <# 585> write_sock stream 0x8065734
has closed socket  
slave1 enbd-server: enbd-server   551: <#1957> talk_hello Introduction
failed: Invalid argument  
slave1 enbd-server: enbd-server: server (0) set default signal handlers
for slave server 548  
slave1 enbd-server: enbd-server: server (0) set default signal handlers
for slave server 551  

The client does not get any errors (at least under the IO load I'm
subjecting it). Here's nbdinfo:

It's not necessarily a show-stopper, as there are no errors generated on
the client, but could it be? And what do they mean?

Thanks
