I get nearly identical errors with Samba 2.0.7 on RedHat 6.1 (updated).  I
maintain at least four other Samba servers with nearly identical
configurations, and none of them have this problem.  I have re-installed
Samba with no improvement.  Restarting samba doesn't help me, either.

It has been suggested to evaluate for any defective hardware, but I don't
have other network problems, and I don't believe it to be faulty hardware.
Methinks there is a bug in lib/util_sock.c in the write_socket_data routine.

I'm using 3Com 3C905B/C ethernet cards in the Samba server.

My errors don't appear every six minutes.  They appear at fairly random
intervals.

Here's my log...
