libvirt users - Jan 2012 - Unable to close open libvirt connections

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()
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.

conn.close() returns the number of references to connection object;
So if the latter example returns 1 it is right as you still have domain
object which you obtained via lookupByName(). So you need to destroy
that object prior to closing connection.
