[Fatal] puppet(3.8.7)The puppet changes the contents of the configuration file or becomes a directory

If a large number of puppets are requested by the puppet server, when the puppet server's CPU load is too high and returns 502,503, the puppet client (3.8.7) has a chance to change the configuration file content and directory

PUPPET CONFIG
class redis( $redis_config ) {

realize(
Package["redis-server"]
)

file {
"sys-redis":
name => "/etc/redis.conf",
mode => 0644, owner => root, group => root,
ensure => present,
force => true,
source => [ "puppet://${puppet_server}/redis/$redis_config/redis.conf",
"puppet://${puppet_server}/redis/default/redis.conf", ],
require => Package["redis-server"],
notify => Exec["restart-redis"],
}

exec

{ "restart-redis": command => "service redis restart", require => Service["redis"], refreshonly => true, }

service

{ "redis": ensure => running, enable => true, hasrestart => true, require => [ Package["redis-server"],File["/etc/redis.conf"] ], }

}
