Check this link:

http://www.barnettsystems.com/created/hpux/cronqueue.html

It refers to the file /var/adm/cron/queuedefs

which defines the maximum number of at or cron jobs is controled by the queuedefs file.

The b queue, for batch jobs, can have
up to 2 jobs running simultaneously. Those jobs will be run with a nice value of 2. If a job cannot be run because too many other jobs are running, cron will wait 90 seconds before trying again to run it.
