I refer to Google's ESF project code to handle NOTIFY events, but after my notifyQueue is set to QOS_CLASS_BACKGROUND, the process memory gets larger when a lot of events occur. Is there any way to fix this without affecting performance The code is as follows： notifyQueue = dispatch_queue_create("notify",dispatch_queue_attr_make_with_qos_class(DISPATCH_QUEUE_CONCURRENT_WITH_AUTORELEASE_POOL,QOS_CLASS_BACKGROUND, 0)); if (msg->action_type == ES_ACTION_TYPE_NOTIFY) { es_message_t *copied_msg = [self copy_message:msg]; if (!copied_msg) { return; } dispatch_async(self->_notifyQueue, ^{ @autoreleasepool { [self handle:copied_msg]; [self free_message:copied_msg]; } }); }

I have an ESF Client process, and this process handles AUTH event in one multi-thread, at this time, if the Client process exits abnormally, will the AUTH event not be handled, thus causing the system to freeze

I have a need to do a coverage test for the networkextension function code implemented by the system extension, but I don't know how to implement this method. For example, how do you use gtest or how do you use xctest to achieve these capabilities? If you know, please let me know. Thanks
