Cannot run 2 mendix apps on linux about m2ee-tools

[hvisage]

(1) What is the Java errors?
(2) you did make sure they are on different ports or IPs?

#(1) this is the error log:

#(2)I'm sure 2 apps run on different ports.

[hvisage]

hmmm... double check the adminports are also different

[evertsc]

• Make sure all ports are different (runtime and admin)
• Configure each app with a different *nix user with their own directory structure for the app and m2ee.yaml
• When you run apps that need different java versions (mx7 uses java8, mx8+ uses java11), make sure to set the "javabin" correctly in your yaml
