Can I know how to gracefully stop tpm2-abrmd daemon or force to stop it?
From the log below, I see the deamon was not able to be stopped and auto restarted.
[root@hostname-1 ~]# service tpm2-abrmd stop
Redirecting to /bin/systemctl stop tpm2-abrmd.service
(It takes about 3-5 minutes and returns back to console)

I think if you just kill it, perhaps kill -9 since its not behaving, the parent process
will restart it.
I wonder why it's misbehaving and not responding to the signal.
Linux services are not my forte, so that might be bad advice. I hail from the Android
world, so my knowledge
here is limited.
