This is the manager process not getting a reply from the child
process and restarting it, assuming that it is not serving
requests either.

You need to find out why the child process does not reply to pings.

The first thing to do is to increase the managers timeout by increasing
the "cli_timeout" parameter to see if the child process is wedged
or just slow.

Never attribute to malice what can adequately be explained by incompetence.
