How mpm_workers work

[Hemant Chaudhary <hemantdude.chaudhary@xxxxxxxxx>]

Hi all,

In my configuration for mpm_worker, I set following datas

Case 1)

StartServer 3

ThreadPerChild 25

MinSpareThreads 75

In this case, when I start apache I found 5 servers start.

Case 2)

StartServer 6

ThreadPerChild 25

MinSpareThreads 150

In this case, when I start apache I found 8 servers start.

Case 3)

StartServer 1

ThreadPerChild 25

MinSpareThreads 25

In this case, when I start apache I found 3 servers start.

My Query is why two extra server is starting.

Can I change serverlimit?

Thanks

Hemant
