It seems that the TIME+ usage of Init is very high on one server as I can't think why this is. TIME+ is the cpu time the process has taken, right? Here are a couple of snapshots from top a minute apart.

They show that Init's cpu time increase by 15 seconds in a minute, rather high, don't you think?

I compared this to another server I have and Init usage there is 2 seconds. (I believe that both of these are non cumulative set in top).

Could anybody help me to understand why this is and if it can be reduced? Perhaps it is indicative of a minor problem or lack of optimisation?
