I start upgrading from SonarQube version 6.x to 7.x (7.9.4).
Following error occurs during start up.

My SonarQube is running in OpenShift. I consultant the internet about this error and found following solution:
sysctl -w vm.max_map_count=524288 sysctl -w fs.file-max=131072
But on my side, I’m not allowed to run a privileged container. So, this is no way. I also tried to set " -Dsonar.es.bootstrap.checks.disable=true" without any luck.
Du you have any other iedeas?
Thank you very much in advance
