Hmmm. I will be very interested to hear what the outcome of this is,
since I am considering ending up with a similar configuration — modulo a
much more powerful server, sitting further away. ;)
In general, are you happy with the system?

Well, I would try vmstat or dstat running detached on the machine,
probably under screen, so I could disconnect the ssh session.
That should give you nice monitoring, especially logged to a file,
without ssh peturbing things. If it still makes things work you have

My guess would be not, but it might be worth checking for errors on the
interface or possibly a tcpdump.
