Hello

Is there a way to debug this error message?

I get this on some (not all) servers, and they pretty powerful 20 core / 256gb ram servers, with identical hardware/os settings.

This is most likely an issue with the operating systems and/or the limits the operating system supplies for the Java process. Starting with version 2023-01 the application is delivered as a compiled binary and does not need a Java JRE/JDK for running.

Maybe you need to raise your open files from 1024. Linux treats threads as files, maybe thats a hint.

So some quick googleing found this entry: Have you configured your DefaultTasksMax? https://stackoverflow.com/a/72551832

I was thinking the same, but the OS limits seem fine.

BUT, I found out that it does not work on Ubuntu 18.04.4 LTS but works on Ubuntu 18.04.5 LTS and up, all with the same limits. (tried on 8 servers + 2 workstations) So I'm thinking it might be some defaults that changed, which Java takes for granted.

On this system it does not work. even if i have higher limits.
