I was caught out by this when testing a 0.24 system in parallel to my 0.23 one! Fortunately I was able to restore the db from backup before any important recordings were missed.

While different subnets is the safest approach that's not often practical, I have firewalled the mysql 3306 port on my live system from my test system and set a different mysql password for belt and braces peace of mind.
