Sonarqube container fails on Azure AppServices with Elasticsearch node error

SonarQube Server / Community Build
1

I’ve tried to install SonarQube 9.2 Developer on Azure AppServices as a linux container and I get consistent errors around elasticsearch not being able to obtain a lock.

The data folder is mapped to an Azure file share. The region is Australia East.

I’ve also tried to downgrade to older versions and I get the same result.

Interestingly enough, the same deployment onto Azure Container Instance (with the same mapping to file shares) succeeds and runs as expected.

Here is the log from ES:
