Todd,
I'm using Fedora Core 4. The problem seems to have gone away. Not sure what I did to fix it.
I changed this:
mechanisms = plain
I have this set as well. I see this problem fairly often and it usually resolves itself after a few minutes.
I also put the user dovecot in the mail group. That might have fixed it.
I haven't tried that one...
One thing I'd like to suggest is that this error would be better if it had more information about what resource wasn't available.
The error is EAGAIN caused from the socket() system call.
Looking at socket(7), I see this:
It is possible to do non-blocking IO on sockets by setting
the O_NONBLOCK flag on a socket file descriptor using
fcntl(2). Then all operations that would block will (usu�
ally) return with EAGAIN (operation should be retried
later); connect(2) will return EINPROGRESS error. The
user can then wait for various events via poll(2) or
select(2).Near as I can tell, this is what it's supposed to mean, but the error seems to be generated before the O_NONBLOCK gets set.

What OS are you using? I see the same problem, but haven't been able to figure out why yet. I'm running SuSE Linux 9.2 with a 2.6 kernel.
It should mean something like you've run out of file descriptors or sockets, but that doesn't seem to be the case here.
