Why are there <defunct> processes on freshly-booted corosync/pacemaker OpenSUSE 11.4 host?

I have been using the monolithic version of Heartbeat for a few years and I'm working on setting up a Corosync/Pacemaker cluster. I'm currently using two OpenSUSE 11.4 virtual machines under Xen to test with and I'm using the standard OpenSUSE packages.

On a freshly-booted server there are <defunct> processes under corosync:

10859 ?        Ssl    0:00 /usr/sbin/corosync
10865 ?        S      0:00  \_ /usr/lib64/heartbeat/stonithd
10866 ?        S      0:00  \_ /usr/lib64/heartbeat/cib
10867 ?        Z      0:00  \_ [lrmd] <defunct>
10868 ?        S      0:00  \_ /usr/lib64/heartbeat/attrd
10869 ?        Z      0:00  \_ [pengine] <defunct>
10870 ?        Z      0:00  \_ [crmd] <defunct>
10871 ?        Z      0:00  \_ [mgmtd] <defunct>
10873 ?        S      0:00  \_ /usr/lib64/heartbeat/stonithd
10874 ?        S      0:00  \_ /usr/lib64/heartbeat/cib
10875 ?        S      0:00  \_ /usr/lib64/heartbeat/lrmd
10876 ?        S      0:00  \_ /usr/lib64/heartbeat/attrd
10877 ?        S      0:00  \_ /usr/lib64/heartbeat/pengine
10899 ?        S      0:00  \_ /usr/lib64/heartbeat/crmd

Note that although there are defunct lrmd, crmd, pengine and mgmtd processes there are also there are also running copies of all of these except mgmtd.

This problem has been reported to Novell/SUSE: https://bugzilla.novell.com/process_bug.cgi, but no solutions were offered.

Can anyone tell me why this is happening or suggest configuration settings I should look at to keep this from happening?
