I have thought about firewalls and timeouts.  I just have two machines, 
sitting next to each other connected by a switch.  One has Vista, the other 
XP.  I tried running the slon engines on either one.  I also tried changing 
all of the IP settings available.  I also tried adding a linux machine and 
running the slon process on that machine.  In every case, the machine that 
is the slave failed after about 12 - 15 GB with a error 10055 (not enough 
buffer space or enough tcp buffers).  Also, the database I am trying to 
replicate is very simple.  One table, no indexes.  Even the table is simple. 
On serial column as primary key, the other is bytea data.

Any suggestions?
