Old vasd processes still existing after upgrading SuSe Linux Enterprise Server 15 to Safeguard Authentication Services 5.x (4276377)

Old vasd processes are left running after upgrading SuSe Linux Enterprise Server 15 from Safeguard Authentication Services 4.2.x to 5.x.

Run ps -ef to check if there are more than 7 vasd processes running:
# ps -ef |grep vasd


If affected by this issue you will see at least more than one vasd process running with a PPID of 1.
I.E.
ps -ef |grep vasd
root     17078     1  0 12:54 ?        00:00:00 /opt/quest/sbin/.vasd -p /var/opt/quest/vas/vasd/.vasd.pid -w
root     17025     1  0 12:53 ?        00:00:00 /opt/quest/sbin/.vasd -C 2

The remaining processes will be associated with one of these processes as the parent as expected.
You can use the following command to identify which processes are deemed valid.
# /opt/quest/bin/vastool info processes
This will display the parent process and all identified children.

Note that these old vasd processes cannot be killed using systemctl.
