Deadlock happened due to mixed lock order. CREATE/DROP function: wrlock(THR_LOCK_udf) -> lock(LOCK_open) SELECT from view: lock(LOCK_open) -> rdlock(THR_LOCK_udf) Fixed CREATE/DROP function so that LOCK_open does not intersect with wrlock(THR_LOCK_udf). 10.0 is not affected: it doesn't hold LOCK_open while opening view.
