Nasty Data Loss Bug Affecting CouchDB 1.0.0

The folks responsible for CouchDB have found a rather nasty bug in CouchDB version 1.0.0:

Over the weekend of August 7th–8th, 2010 we discovered and fixed a nasty bug in CouchDB 1.0.0. The problem was subtle (cancelling a timer, without deleting the reference to it) but the ramifications are not: once the bad code path is triggered, subsequent writes to the database are never committed. This means there is potential data-loss for users of 1.0.0.

Fortunately, the bug is not effecting everyone and there are instructions to protect yourself while you wait for the patch. To get more information on the bug itself and the temporary fix check out this notice.
