High CPU usage in CA PAM can sometimes be related to internal process sshd.mitm
Release : 3.4, 3.4.1
Component : PRIVILEGED ACCESS MANAGEMENT
When the Session Recording Mount has too many files, this caused sshd.mitm to not exit cleanly and becomes a zombie process consuming CPU.
Solution is to clear up Session Recording Mount so you do not keep too many files.
For a workaround, PAM_3.4.1.09 will install a cronjob to run at midnight GMT/UTC time to kill the orphaned sshd.mitm consuming CPU.
