System in Recovery Mode

Our database was going along just fine this morning when, out of the blue, we started getting the following errors:

FATAL:  the database system is in recovery mode

We are using PostgreSQL 8.1.3 on CentOS.  I was the only person on the machine and had recently started a small batch that had just finished querying and updating the database.  This batch runs constantly and has not been changed in months.

What are the things that could be causing this?

Thanks!
Aaron
