Builds are randomly stuck without any visible reason

Summary

It started around Friday 2023-04-07, then it was ok on Tuesday, but now it happened again. Some of jobs are stuck after executing /opt/tools/java/temurin/jdk-17/latest/bin/jcmd ; the previous week it sometimes happened also with mvn -version

Steps to reproduce

Rerun one of these builds: https://ci.eclipse.org/glassfish/job/glassfish_build-and-test-using-jenkinsfile/job/PR-24376/ https://ci.eclipse.org/glassfish/job/glassfish6_build-and-test_jdk17/ (stuck for 7 hours now, last line is executing maven install plugin)

What is the expected correct behavior?

Build should pass of fail in standard time, not with build timeout.

Relevant logs and/or screenshots

Seems like some network error?
