Requests to JSReport come from physically separate applications that don't "communicate" with each other, so at this stage, there is no queue. Requests go directly to JSReport, and there is no load balancer.
We’ve also noticed that if requests are made from different templates, they start "in parallel" without issues. Seems that only one report per report template is generated at a time.
We have the following setting:
"workers": {
"numberOfWorkers": 8
}
JSReport version: 4.6.0-full
Driver: Cheerio
However, only one report is being generated, and all other requests are queued. Do you have any ideas on what else to check?
