ERRORS

can't read kernel memory

The agent uid does not have permission to read kernel memory, /dev/kmem. Run the agent as root (default case if agent started by inetd (1M) ), or give read permission to the uid the agent is running under.

The error message can also occur if the agent can't find or read the file containing the kernel namelist.
