First, make sure you all are using current 0.24-fixes.  There have been 
some fixes for networking/socket issues.

Also note that it seems that the above problem only happens with 
specific configurations (either differences in hardware (such as chipset 
and/or network devices) or kernel, library, ... version).  I've never 
seen the problem on any of my systems, with any of my distro versions, 
so without a sufficiently specific bug report, I can't debug it, let 
alone fix it.
