It does not looks too off to me given Aleks' configuration: PHP starts off with 5 worker processes (idle). If at least 6 requests come in at the same time then PHP will reach 10 worker processes, because PHP is configured to keep 4 idle processes at all times. A 7th request would violate the minimum number of idle processes. Now if the number of concurrent requests goes down to 4 you will still see the 10 processes, because PHP is allowed to keep 6 idle processes around. Best regards Tim Düsterhus
