The problem is that the proc struct is not locked for: FOREACH_THREAD_IN_PROC(td->td_proc, td0) in the lock and unlock. Either lock the proc before and unlock it after this, in both _utmx_lock() and _utmx_unlock(), or revert the code to 1.2. It's pretty simple. No one needs t look at it, all they need to do is act on information already present. -- Terry
