Hi Philip,
Not sure how the AJS would impact users from viewing and creating reports since the requests are handled by the Processing Servers (CMS, APS, Cache)
If job server child are hung in memory then I assume the server could perform poorly depending on mem/cpu taken - in this case I would suggest adding “–type outproc” in the command line parameters of the AJS. Outporc forces job child to exit memory once it’s finished with the job.
Hope this helps,
Valdrin
