Using Timer to Release Claim on Task

[holein1]

Is there a way to use a boundary timer or other to release a user (unclaim) who has claimed a task? What does one do when a user claims a task but fails to complete it before leaving, etc.?

You can use the solution described in http://forums.activiti.org/content/auto-delegation-without-assigning-task i.e. add timer-boundary-event with  "cancelActivity=false" followed by service task to update task status.
