崩溃在CFNetwork内部的iOS 11上

Question

我每隔几个小时就会看到几十个崩溃的应用程序,仅在iOS 11中.堆栈跟踪没有帮助,我也没有任何线索,因为其余的线程在每个崩溃日志中都做了一些完全不同的事情.因此,我无法弄清楚究竟是什么触发它.其他人看到这个？

它似乎总是这样:

TCPIOConnection::_handleTLSEvent(nw_tls_context*, tls_handshake_message_t, void () block_pointer, bool) + 640

在所有这些崩溃日志中似乎还有一个共同的线程,我怀疑它来自Fabric本身.还有其他人看到这个吗？
