So,
nr_workers == 15,
nr_idle == 0,
nr_running == 0,
That means one worker must be playing the role of manager by executing
manage_workers() whic his also responsible for kicking off the
rescuers if it fails to create new workers in a short period of time.
The manager is identifier as the holder of pool->manager_arb and while
a manager is trying to creat a worker, pool->mayday_timer must be
armed continuously firing off every MAYDAY_INTERVAL summoning rescuers
to the pool, which should be visible through the pool_pwq->mayday_node
corresponding to the stalled pool being queued on wq->maydays.
Can you post the full dump of the pool, wq and all kworkers?
Thanks.
