There are multiple defects in NetworkWorker and the related parts since the C++ rewrite. 1) NetworkService holds a reference to NetworkWorker and never releases it. It has to wait until the cycle collector comes up to resolve their ownership loop and free NetworkWorker manually. However 2) nsINetworkWorker::shutdown is never called, and that leaves everything living till the end, inclusive of that gNetdConsumer in Netd.cpp. 3) when GC comes to free NetworkWorker, it calls its parent destructor ~NetConsumer(), which in turn calls ~RefCounted<NetdConsumer>(). Having a valid gNetdConsumer in Netd.cpp follows its refCnt is not zero and this triggers an assertion in ~RefCounted<NetdConsumer>(). So, some obvious treatments here. A) NetworkService should call nsINetworkWorker::shutdown upon receiving a shutdown observer event and release the reference to NetworkWorker. B) NetworkWorker should never be double ref-counted. Move NetdConsumer implementation into a separated class.
