Correct. That is why I suggested it be done in an external persistent
daemon process in the first place. You can't guarantee that Apache
will not decide to kill off its child processes. Here you illustrate the
problem for where MaxRequestPerChild is used, but it can also kill
off child processes if it has excess child processes over some limit
as well and the child processes are being under utilised.
