Hi. Please help me troubleshoot this error. I use Mendix Studio and I get “the daemon has disappeared” error every 5th build or so. There’s nothing suspicious in the daemon log, looks like the process terminates before it can print something to the log. The newest “hs_err_pid*.log” is 6 months old. The tasks don’t matter. Sometimes it’s cleanup, sometimes it’s build. It may fail twice in a row or it may succeed. This is the only java app that crashes on my PC, the others work fine.
Currently I use gradle-8.5 bundled with Mendix Studio. It uses this command lines:
"C:\Program Files\Java\jdk-11.0.20.1+1/bin/java.exe" "-Xmx64m" "-Xms64m" "-javaagent:C:\Program Files\Mendix\gradle-8.5/lib/agents/gradle-instrumentation-agent-8.5.jar" "-Dorg.gradle.appname=gradle" -classpath "C:\Program Files\Mendix\gradle-8.5\lib\gradle-launcher-8.5.jar" org.gradle.launcher.GradleMain --info --project-dir "C:\Users\basin\Documents\Mendix\Book_Production-main\deployment" clean-custom-classes compile package

I don’t have full control over how it’s launched by the IDE. Even the project file is generated on the fly and I don’t know the contents.
My gradle.properties and init.gradle in %USERPROFILE%.gradle are empty.
From today’s error:
The message received from the daemon indicates that the daemon has disappeared.
