But after creating the first few, they are seeing an error. They can start a tomcat for the batch work, plus 2 tomcats for users, but any further tomcats fail with this error: Has anyone seen this & know how to get around it?
There has been an issue; please consult your system administrator
Not enough details to comment on this. The generic error normally means something wrong on the server side, share the problem tomcat instance logs so that we can help you out. BTW, not sure about your goals here, think about using Kubernetes, no manual clone of nodes. You can scale up and down with one single command: https://github.com/pegasystems/pega-helm-charts
