Hi,
I have been accessing gmail from a standalone plan 9 terminal (pulled
from sources and rebuilt kernel a few days ago) under vmware fusion
3.1.0. When I tried again recently:
term% upas/fs -f /imaps/imap.gmail.com/my_email@gmail.com
I enter my password and then
a black square appears on the screen and "soverflow for fx->in" is
printed repeatedly. This goes on for some time and then errors like:
download 10423: short read 3084755 != 3571948: Hangup
download 10424: i/o error: Hangup
download 10425: i/o error: Hangup
download 10426: i/o error: Hangup
download 10427: i/o error: Hangup
are printed in the window.
I've seen this before, I previously had 4000 emails in my inbox and I
got the these errors trying to open it. Now I have only 250 (2 or 3
weeks worth) I have also only seen the "soverflow for fx->in" on
vmware. On my native plan9 box I have only seen the hangup errors. I
also seen the soverflow error when doing a pull (a big one) under
vmware.

what's happening is that the printing of "soverflow for fx->in"
is wasting so much time that the imap server gets bored and hangs
up. i think incrementing a counter, rather than printing makes
more sense. the version of pc/devether.c in 9atom does just that.
a bigger question is why you're getting queue overflows.
it could be that the virtualization is screwing with queue sizing.
nupas may also be helpful for big imap mailboxes;
unless viewed, email only gets downloaded once.

This is really dragging out for 30 minutes?
