Description Mike Cvet 2006-07-27 20:40:20 UTC
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.

Comment 1 Mark Wielaard 2007-07-10 09:42:57 UTC
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.
