Number of program instances

[danweber]

What controls the number of started instances of qmail, httpd, named and other tasks? My http.conf file shows two initial instances but when I check I see 10.

I though named would probably have an instance for each ip address but there are more instances running than that.

Also mysql has a lot of instances running.

I presume that the additional instances will help to serve requests but there must be a tradeoff where too many instances would compete with limited system resources and actually make things slower.

Does anyone know how to control the number of instances for these programs?

Thanks
Dan

Wow, I thought I had deja vu. Just saw this on the WHT forums as well. Since you got your answer there, I won't repost....

But for any other readers who may be interested:
