In my logs, "I/O error on connection" typically has a line soon       
before it with payload something like "collect: premature EOM:        
Connection reset by <foo>". This certainly would indicate that it's   
not you. Are you seeing anything of the sort?"                        

I also think it's probably network issues, or possibly flaky MTAs on
the distant end, and that adding RAM won't fix that. Adding RAM *will*
help with other things, though, and especially so if you use ramdisk 
for your temp directory.
