Josh Paetzel aedc925301 MVF: 313876 ... 7504 kmem_reap hangs spa_sync and administrative tasks illumos/illumos-gate@405a5a0f5c https://github.com/illumos/illumos-gate/commit/405a5a0f5c3ab36cb76559467d1a62ba648bd80 https://www.illumos.org/issues/7504 We see long spa_sync(). We are waiting to hold dp_config_rwlock for writer. Some other thread holds dp_config_rwlock for reader, then calls arc_get_data_buf(), which finds that arc_is_overflowing()==B_TRUE. So it waits (while holding dp_config_rwlock for reader) for arc_reclaim_thread to signal arc_reclaim_waiters_cv. Before signaling, arc_reclaim_thread does arc_kmem_reap_now(), which takes ~seconds.
