High CPU usage in CA PAM caused by internal process "sshd.mitm" process consuming high CPU

Products

• CA Privileged Access Manager (PAM)

Issue/Introduction

High CPU usage in CA PAM can sometimes be related to internal process sshd.mitm

Cause

When the Session Recording Mount has too many files, this caused sshd.mitm to not exit cleanly and becomes a zombie process consuming CPU.

 

Environment

Release : 3.4, 3.4.1

Component : PRIVILEGED ACCESS MANAGEMENT

Resolution

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.
