[libvirt-users] libvirt: XML-RPC error : Cannot write data: Broken pipe

Hi all, I think it's a bug, when call virDomainGetState after "service libvirtd stop", I receive signal SIGPIPE. I want to know how to avoid this problem? And Other interfaces will also encounter this problem？ Below the bt information: Below some information about my hypervisor: root@ubuntu-05:/datapool/zhuohf# virsh -v 3.4.0 root@ubuntu-05:/datapool/zhuohf# qemu-x86_64 -version qemu-x86_64 version 2.9.0 Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers
