I've been hitting the following assertion several times a day: // Now send along the message. kern_return_t kr = mach_msg(header, MACH_SEND_MSG, header->msgh_size, 0, MACH_PORT_NULL, MACH_MSG_TIMEOUT_NONE, MACH_PORT_NULL); if (kr != KERN_SUCCESS) { LOG_ERROR("Failed to send message to real exception port. %s (%x)", mach_error_string(kr), kr); ASSERT_NOT_REACHED(); } It typically happens after the web process hits an assertion failure of some sort. Having the UI process die when a web process dies interferes with development.
