Setting CUPS "MaxJobs 0" in RHEL

Issue

• There have been a few times that our print queues have max'd out with the error "lp: Too many active jobs". I have read that you can set the directive MaxJobs 0 to keep the queue from maxing out. I have the following questions:
  • Are there any negatives to setting MaxJobs 0?
  • If there negatives, what are they?
• We ran into issue yesterday where we reached default max job limit of 500 and our application was not able to spool more print jobs and production came to a halt. I fixed this by setting MaxJobs 0 and disabling the restriction. I'm just looking for best practices for the setting of MaxJobs.
• The lpstat command is not returning, or takes a very long time (several minutes) to return.
