FogBugz maintenance discovered an expired lock - Delete 11/01/2010 01:27:39 PM (GMT+00:00): An expired lock was broken by the FogBugz maintenance service. If this error persists, it may mean that the FogBugz heartbeat is failing.
On going to /heartbeat.php :
Fogbugz heartbeat is locked.
If you are sure there are no other processes running heartbeat, you can break the lock and reload heartbeat
After clicking this link, get a blank page- then refreshing this gets the same error as above.
Linux/MySql system that was working fine until yesterday.
