Gmail

Is anybody else having trouble with gmail lately?  I keep getting a pop up box titled Error which says:

Oops... a server error occurred and your email was not saved. (#103)

[or not sent, or whatever]

But then the email seems to have been saved, or sent, or whatever.  I found a thread on Google Groups:

http://groups.google.com/group/Gmail-Help-Message-Delivery-en/browse_thread/thread/dd559ea4f36765db

But it doesn't say much.
