Scenario:
Installing the Access Manager installs the updated version of rsyslog and its dependencies. In some cases, the dependencies may not be updated to the latest version as compared to rsyslog. This results in failure to start rsyslog.
Workaround:
Update the ryslog dependency, libfastjson to the latest version using zypper or yum depending on RHEL or SUSE respectively.
NOTE:Updating the Operating System may also result in failure to start rsyslog.
