Vast quantity of our Secondary site servers reported SMS_OUTBOX_MONITOR and SMS_INBOX_MONITOR components have gone critical, but there are no status messages.

Quick look at the inbox\outbox logs, shows -2700 for the next polling cycle.

Waiting until the next polling cycle in -2700 seconds from now.

You can restart the components or restart the SMS_EXECUTIVE to fix this.

It seems to be due to DST (timezone) changes. We rolled out http://support.microsoft.com/kb/959257 to our Primary site servers last week, assume this is why the primary site servers are not complaining as the secondaries are.

See this thread on myITforum for more info, it helped us!
