problems communicating with gmail smtp servers... anyone else?

[Alex Teslik]

My logs have recently started showing strange errors while trying to
communicate with Google's gmail servers:
Sep 14 17:16:36 gouda sm-mta[22791]: m8EKundi019579: SYSERR(root): timeout
writing message to gsmtp183.google.com.: Resource temporarily unavailable
Sep 14 17:31:27 gouda sm-mta[23416]: m8EKundi019579: SYSERR(root): timeout
writing message to gmail-smtp-in.l.google.com.: Broken pipe
Sep 14 17:36:29 gouda sm-mta[23416]: m8EKundi019579: SYSERR(root): timeout
writing message to alt2.gmail-smtp-in.l.google.com.: Resource temporarily
unavailable
Sep 14 17:41:20 gouda sm-mta[23416]: m8EKundi019579: SYSERR(root): timeout
writing message to alt1.gmail-smtp-in.l.google.com.: Broken pipe

originally I thought something was wrong with Google's servers, and that it
would right itself quickly... but that hasn't happened. Is anyone else
getting these error messages in their logs? Does anyone have any ideas I
could check to make sure my server isn't the problem?

Thanks
