Thank you for the nice reports.
I would like to know what customizations in jsreport.config.json have you done except the mongo store?
What version of jsreport do you use?
Is it xlsx recipe or html-to-xlsx recipe you use?
Do you run jsreport inside docker or it runs directly?
Do you persist outputs using reports extension?
Can't your code in script or templating engine memory leak? In case you use http-server strategy.
In case you use
http-server strategy for templating engines/scripts. Could you try to switch it back to the default
dedicated-process temporary? Just that we try to isolate the problem.
