If you have the "show memory" and "show registers" actions attached to a process on an event and these windows come up; x-ing these two windows brings up this error; when the process that they are both observing should become unblocked and continue. {frysk.proc.LinuxTask@1087e40,pid=11431,tid=11431,state=BlockedSignal,sig=0} in state "BlockedSignal" did not handle handleDeleteObserver frysk.proc.State.unhandled(FryskGui) frysk.proc.TaskState.handleDeleteObserver(FryskGui) frysk.proc.Task.handleDeleteObserver(FryskGui) frysk.proc.TaskObservation.handleDelete(FryskGui) frysk.proc.ProcState$3.handleDeleteObservation(FryskGui) frysk.proc.Proc$8.execute(FryskGui) frysk.event.EventLoop.runEventLoop(FryskGui) frysk.event.EventLoop.run(FryskGui) frysk.gui.Gui$4.run(FryskGui) java.lang.Thread.run(libgcj.so.7)
This should have been fixed a long time ago when bug #3571 was fixed: 2006-12-06 Mark Wielaard <mark@klomp.org> Fixes bug #3571 * frysk-core/frysk/proc/TestTaskObserverInstruction.java: Don't explicitly unblock before deletion of observer. * LinuxPtraceTaskState.java (BlockedSignal.handleDeleteObservation): Explicitly unblock observer.
