Why? That looks like a very strange thing to do.

So every minute cron will run a shell script, and then wait for it to 
finish. Each shell script forks a subshell in the background and then 
exits, so cron no longer waits. The subshell is reparented to process 1. 
When it exits, it will become a zombie until process 1 reaps its status.

Why are you running the subshell? Why do you background it? Why are you 
throwing away any error output from chpst/runsvdir?

What happens if your cron line is:

*/1  * * * *   chpst -L /var/www/soft.p/html/.lib/var/.lock.service runsvdir /var/www/soft.p/html/.lib/var/.lib/service/

?

Why are you starting a new runsvdir every minute?

What are you actually trying to achieve? - perhaps someone can suggest a 
less "unusual" design.
