Description of problem:
Not exactly sure how to reproduce the problem. I am doing quite a bit of heavy
development that uses libvirt. The libvirtd.log file prints out:
11:25:21.784: 24375: error : virNetServerDispatchNewClient:220 : Too many
active clients (20), dropping connection from 127.0.0.1;0

A second process is spawned by libvirt as well:
root 22049 24375 0 11:49 ?00:00:00 libvirtd --daemon
root 22353 22671 0 11:58 pts/400:00:00 grep --color=auto libvirt
root 24375 1 2 11:00 ?00:01:40 libvirtd --daemon
kill -9 of the non-init parented libvirt unsticks the system ie:
[root@beast libvirt]# kill -9 22049
Then things start working again.
Version-Release number of selected component (if applicable):
[root@beast libvirt]# rpm -qa | grep libvirt
libvirt-0.9.6-2.fc16.x86_64
libvirt-python-0.9.6-2.fc16.x86_64
libvirt-client-0.9.6-2.fc16.x86_64
How reproducible:
hard to reproduce
Steps to Reproduce:
1. execute vm starts/stops
2.
3.
Actual results:
libvirt launches a second process and wedges
Expected results:
libvirt should not wedge
Additional info:
killing the second process unwedges libvirt

Not sure if too many active clients error from log is related to the
second process being spawned. They may be separate events. I have
changed my program behavior not to use so many sockets, but occasionally
the software still wedges.

Notice the CPU time on the forked process is quite high. This ps was
taken ~1-2 minutes after the system wedged.

ignore comment #2, the 2nd process in the list wasn't the forked child.
