Hello, I was getting the following error in syslog: libvirtd: 21:19:12.116: 10955: error : qemudDispatchServer:1355 : Too many active clients (20), dropping connection from 127.0.0.1;0 I investigated a bit and tried the following in a python console: import libvirt ~~~~ conn=libvirt.openReadOnly("qemu+ssh://HOST_IP/system <http://10.16.71.1/system>") //now check the no. of connections (by lsof|grep ESTABLISHED in the HOST), the count will increase by 1 conn.close() *//the count will decrease by 1, it returns 0* ~~~~ conn=libvirt.openReadOnly("qemu+ssh://HOST_IP/system <http://10.16.71.1/system>") //now check the no. of connections, the count will increase by 1 dom=conn.lookupByName("sowmya") print dom.info <http://dom.info/>() conn.close() *//the count will not change, it returns 1* * * This is creating a lot of trouble to me but the reason is unknown. If someone could please point me out, if i am missing something. -- Jatin
