I am using Fedora 16 with default python2.7.2 installed, and found
sometimes vdsm hanged at
vdsm/storage/misc.py, func execFunc:
        p = subprocess.Popen(command, close_fds=True, cwd=cwd,
                        stdin=infile, stdout=outfile,
                        stderr=subprocess.PIPE,
                        env=env)

     Stopped command could be anything, most likely is
     "Thread-12::DEBUG::2012-04-12
     11:18:08,995::__init__::1241::Storage.Misc.excCmd::(_log)
     '/usr/bin/sudo -n /sbin/iscsiadm -m session -R' (cwd None)"
during vdsm booting up procedure. This happens only when an other
thread is started at the same time by calling
threading.thread.start(), which I found in clientIF._init():
     self._hostStats.start()

   When it happens , there would be two vdsm showed in ps command,:
vdsm     13794     1  0 11:18 ?        00:00:00 /bin/bash -e
/usr/share/vdsm/respawn --minlifetime 10 --daemon --masterpid
/var/run/vdsm/respawn.pid /usr/share/vdsm/vdsm
vdsm     13797 13794  0 11:18 ?        00:00:00 /usr/bin/python
/usr/share/vdsm/vdsm
vdsm     13837 13797  0 11:18 ?        00:00:00 /usr/bin/python
/usr/share/vdsm/vdsm

     Does anyone could give some idea about it? I made my own testing
     .py program calling misc.execFunc in one thread, and starting an
     other thread by start() in main thread, same thing happens with
     little chance, so I guess it is a bug in python threading and
     pipe, planning to change vdsm threading class to work around
     this.

Do you have abrt package installed?

yes, and removed all abrt packages testing again, problem still happens.
[root@oVirtPC xiawenc]# rpm -qa | grep abrt
[root@oVirtPC xiawenc]#

[root@oVirtPC xiawenc]# rpm -qa | grep vdsm
vdsm-cli-4.9.6-0.68.git19981e1.fc16.noarch
vdsm-4.9.6-0.68.git19981e1.fc16.x86_64
vdsm-debuginfo-4.9.6-0.68.git19981e1.fc16.x86_64
vdsm-python-4.9.6-0.68.git19981e1.fc16.noarch

   Adam also metioned abrt package before, what problem it would trick?
