Description From Tino Vázquez 2007-11-14 05:37:49

When the scheduler dies, there is a race condition that can result in gridway
getting blocked. It is non trivial to reproduce, since it happens when the DM
is recovering the jobs and sending them to the scheduler, and also from other
thread the core requests to schedule another job. The solution would be to stop
the scheduling until the recovering is done.
