[libvirt] libvirt python binding and strange errors in logs

I'm use libvirt-python binding to export some metrics to ganglia from libvirt. python code http://paste.debian.net/422944/ when this script is running i get many erros in libvirtd.log like this: error : virNetSocketReadWire:1613 : End of file while reading data: Input/output error При этом открывается сокет: virNetSocketNew:277 : RPC_SOCKET_NEW: sock=0x7fced8036ae0 fd=27 errfd=-1 pid=0 localAddr=::1;16509, remoteAddr=::1;39962 As i understand libvirt try to determine client alive and fails, my code properly close libvirt connection, but may be it not freed? Or something else broken with my code? i'm use libvirt-python from 1.2.1 to 1.2.9 and libvirt from 1.3.0 to 1.3.3 -- Vasiliy Tolstov, e-mail: v.tolstov(a)selfip.ru
